There is an old Chinese proverb; “Failure results not from the length of the journey or the height of the mountain but the pebble in one’s shoe.”
We have all had it at some point – the pebble that is.
We are running or walking or hiking and feel a small irritant. We think to ourselves that maybe our sock bunched up. But, after a bit, we realize its something else. So we move our foot around a bit or kick it up against a rock or log, or maybe sideways on the ground. The hope is that that kick will move the irritating thing to the side where we won’t feel it.
Sometimes it works for a while. But it always comes back. We are always better off to stop, take off your shoes, and clear whatever the problem is. Even the smallest pebble can cause problems. It can start with a hot spot and develop into a blister. It can cause a hole to develop in the sock. It can tear into the insole’s covering.
So stop and remove it.
I remember a few years back when I was at the Gold Rush Adventure Race and encountered a similar situation. One of the racers came into the transition area and in the process of changing socks, I told her I’d clean out her shoes. The race route had taken runners through muddy areas and some had gone down into her shoes.
As I used my hands to clean inside her shoes, I found very rough hard edges under both heels. I thought it was a defect or tear in the insole. Surprisingly, it was hardened mud that was so hard, it took a lot of pressure to remove it from the insole. This must have hurt through the socks – but the racer had not bothered to clear out her shoes.
In reality, it might be a pebble – or mud. In either case, you are always better off to take a moment and get rid of the irritant.
Of course, I have to recommend gaiters for trail running. They can keep the pebble out in the first place!
Efraim Manzano caught my eye a few weeks when I learned that he had run the HURT 100 in Hawaii in Crocs. I messaged in on Facebook and we chatted back and forth a few times. He lives in Honolulu, Hawaii and has been running all his life, but running races for the past 10 years, and ultras for five years. Efraim said he’d be happy to share some tips about running in Crocs and how he came to use them rather than trail shoes. Here are the questions I asked Efraim and his responses. I added content about Crocs in a couple of sections.
Question: How often do you run in Crocs?
I run with my Crocs all the time.
Question: Do you also run in road or trail shoes?
No road or trail shoes, I only run in Crocs.
Question: What style Crocs do you use?
I use the Classic Beach style for road running (Marathon, Ironman) and the Bistro style for trail running. The Classic model has vent holes both on top of the toebox and around the side of the toe and forefoot. These are good for road races and help ventilate the feet. Crocs on average weigh 11 ounces per pair.
Question: How did you get started in wearing Crocs?
Back in 2007 before the Honolulu Marathon a friend of mine dared me to run in a Bahag (Filipino G String) or loincloth, commonly used throughout the Philippines before the arrival of the European colonizers, and which is still used by the indigenous tribe of the Philippines today. Shoes looked awkward with the Bahag so that’s when the Crocs came about and been I’ve been running in them ever since then.
Question: Do you use them in training and in races?
Yes! I always train in Crocs and use them in all my races.
Question: What’s the longest run you have done in them?
My longest run in Crocs is 100 miles.
Question: How long will they last (miles/time)?
They last a long time, approximately 1000+ miles, I still have the Crocs that I’ve use back in 2007 Honolulu Marathon and still use that pair for training.
Question: Do you wear socks with them?
Yes I always wear socks with them. I use any socks – even use socks I buy from Costco.
Question: Because they fit loosely, how do you keep them on your feet? Do you use the strap around the heel?
My feet always swell up after running anything over a marathon distance so I like my Crocs to be loose and yes, I always use the strap around the heels for insurance. The swelling that I’m talking about is the normal swelling of the feet when you are running or cycling. With regular running shoes it would bother me a lot because my feet get squeezed in there – so I like the looseness of the Crocs specially on those long run like marathons and especially on those ultra runs.
Question: Because they are fairly smooth on the bottom, how are they on trails?
I use the Crocs Bistro style on the trail. Crocs Bistros are designed specifically for those in the food service, hospitality and health care industries and has the Crocs lock slip-resistant tread. It works pretty well on the trails, even muddy trails. The Bistro also has an enclosed toe and forefoot design without the holes common to other Crocs designs like the Classic. The Bistro also has a more cushioned metatarsal area in the forefoot. The Bistro Pro has even more cushioning, an adjustable heel strap, and beefed up toe and heel bumpers for protection. The Bistro sells for about $45 and the Bistro Pro for $60.
Question: Have you had problems with rocks, dirt and trail grit getting inside?
At the HURT 100 a couple weeks ago when I feel something inside my Crocs I don’t let it bother me. I just stop running and take my Crocs off and shake it out. It gives me three seconds rest and recovery! The enclosed toe design helps keep junk out of the toebox.
Question: Have you had any foot problems from wearing them?
By the grace of God I never had any foot problems from wearing them, I had more problems before when I use to wear those high-end shoes. About blisters, it all depends if the socks got wet, this past HURT 100 I didn’t got any blisters. I changed my socks every loop so I didn’t get any blisters, but in the previous races that I’ve done before I’ve had blisters from the Crocs – especially on the rainy day.
Note: Thank you John for giving me this privilege to share my experience using the best and the most comfy running/cycling shoes in the world!
There you have it. You can run in Crocs! Thanks Efriam for sharing your story with our readers. I’ve heard of people wearing Crocs before, but this had never made a connection to do an interview. I’ll continue to use the three pair I have at home. Maybe the next pair I get will be the Bistro Pro. If you want to leaner more about the entire Crocs line, check them out at Crocs.com.

Superfeet’s Wool Insoles
I have liked Superfeet’s insoles for many years. Last year I was sent a pair of Superfeet’s Wool Insoles to try. Before talking about these insoles, a bit of information about the design of their insoles is in order.
If you need good support in an insole, look at a Superfeet insole. They are designed to work with the volume and fit profile of your feet. The volume is the amount of room needed inside your shoe to accommodate your feet, the sock and the insole. The fit is the amount of support and the shape of the insole under the foot and heel. With these insoles, you don’t get a one-size-fits-all type of insole. This is important if you have feet that require heel or arch support, like an insole with a well-defined heel cup, or simply want a insole that will hold up for a long time.
Their volume and fit profile is based on three types of feet – low, medium, and high fit; and low, medium, and high volume. Low is the most common foot type, medium fits in most types of footwear, and high gives the most support. Fortunately, the Superfeet website shows how each insole is designed for volume and fit, which makes it easy to find the best insole for your feet.
Their merino wool insole would be a good choice if you want a bit of added warmth in your shoes. The insole has the typical plastic support from the heel and mid-foot. Over that is the full-length foam that supports the top layer of merino wool. I measure these layers at about 1/8th inch each. That gives some added insulation from the cold coming up from the ground. The wool thickness is generous. They are very comfortable. You can get the merino wool insole in grey, which is thicker and made for high fit and volume, or white, which is made for medium fit and volume. All of the Superfeet insoles can be viewed on the Superfeet website. After that, you can purchase them from Superfeet, Zombierunner.com, your local running store, outdoors store, or other online stores.
They key with any insole is to try them in your shoes. Some are thicker and will reduce the amount of space in your shoes for your socks and feet. If that’s the case, you can either move to a thinner and lighter weight sock, or find an insole with less thickness.
So make sure you try an insole in your shoe before going out for your long run or hike. Wear them around the house for a while and see how they feel.

Heel blisters are quite common – although they shouldn’t be.
Today’s post shows one participant’s feet at the 2014 Amazon Jungle Marathon.
If you look closely at this picture, you’ll see two heel blisters, both on the outside of the runner’s feet. The right foot blister is large but is not blood-filled. The blister on the left heel, however, is very large and filled with a large amount of blood.
It’s easy to think these are normal blisters – but their size makes they abnormal.
In my experience, heel blisters are caused by the constant shear when either 1) the heel is moving up and down inside the shoes’ heel, or 2) by the constant movement at the place where the shoe’s insole touches the inside of the shoe. Over the years, the majority of heel blisters have been the latter. One of the characteristics of this “insole/shoe junction” blister is that they often are flat across the bottom. The blister starts at the point where the insole’s edge at the side of the heel touches the inside of the shoe. That’s what makes the flat line at the bottom. Then the blister forms upward as the fluid forms and it grows. Given enough time and movement, you’ll get blood inside.
These are relatively simple to patch. The skin must be cleaned with alcohol wipes, and then the blister can be lanced and drained. Depending on the size of the blister, you’ll need to apply some type of blister patch. The bottom line is that you need to have something over the blister to protect the skin and prevent the top layer of skin from tearing off. For these, I would use strips of kinesiology tape (my preference is either StrengthTape or RockTape H2O) with antibiotic ointment over the blister to keep the tape from sticking to the skin. The larger the blister, the harder these are to patch but it can be done.
You are better off to prevent these blisters in the first place.
Start with the fit. Make sure your shoes hold your heels in place with just a little movement.
Check your shoes and insoles for rough and/or thick edges at the inside and outside of each heel. Side blisters are much more common than the back of the heel. If the insole has a large thick edge, replace them. If the shoe’s fabric is worn into a hole, you are due for new shoes. Under the fabric is generally a plastic edge of the shoe’s heel counter – the plastic that curves around the heel from side to side.
Engo Blister Prevention Patches are perfect for to help prevent these types of blisters. These patches are super slick. Either the small or large oval can be applied to the inside of the shoe and cover the offending edge of the insole/shoe junction. Clean the inside of the shoe and insole first. I work the patch with my fingers to form a curve to fit with area I need to cover. Then remove the backing and apply the center of the patch first and then push the top and bottom of the patch into place. Rub it a bit to assure adherence.

Here are a few foot care tips I wrote to help runners at the Amazon Jungle Marathon. I’ll be there in a few weeks to help with foot care on the medical team. The tips are valuable for anyone doing a 24 hour race, a multi-day event, an adventure race, or a long backpack. Remember, your feet will carry you day to day only if you take care of them.
Start with good toenail care. Trim your nails short and then use a file over the front edge to remove any rough edges. File the tip of the nail so when you run your fingertip over the tip of the toe and over the nail, you don’t feel any rough edges. You can also file the top of the nail if it’s thick. Coming to the race with bad toenails will ensure toe blisters and black toenails.
Make sure your shoes fit well. Have enough room in the toe box for your toes to wiggle. Your feet may swell over the race and you don’t want shoes that are too tight. Some shoes, like Hokas, retain water and become heavy over the days, as they are wet so much of the time. Wet and waterlogged shoes are heavy.
Get good socks. Don’t show up with cotton socks. Socks made with Coolmax or wool are good choices. Injinji toe socks are great. Have several pair and wash then after each day’s stage or have one pair per day. Also don’t show up with old socks or ones with holes in them.
Do whatever you can to reduce any calluses. Getting a blister under a callus can be painful and it’s very hard to find the pocket of fluid for draining. After showering, use a callus file or pumice stone to shave the callused skin from your feet. Then apply some callus cream. This is something that should be done several times a week. Calluses are the result of friction and pressure between your shoes and feet. Make sure your shoes will drain water.
Shoes that hold water inside will increase the maceration effect of your feet being wet to long, leading to wrinkled and soften skin that can fold over, crease, and split open. Check this by filling your shoes with water and seeing whether it will drain out. You can heat a nail (at least 1/8 inch round) or an awl and make several holes at the inside and outside arch, and the heel of your shoes. Learn how your feet respond to being wet for long periods. Do some long walk or runs three to six hours long with wet feet. Try several products like Desitin or similar cream for baby bottoms that works to control moisture on the skin. Google “baby bottom cream” to see many options.
Do not skimp corners on your foot care kit you need to carry in your pack. Have several yards of a good quality tape, several needles to drain blisters, and learn how to drain and patch blisters. The medical team will try and help with your foot care needs, but we can become overwhelmed by the number of people wanting help. Part of your responsibility as a runner is to know how to do good foot care.
Carry a good pair of camp shoes to wear in the camp after each day’s stage. You don’t want to walk around barefoot and doing so will destroy the taping or blister patching done by you or the medical team. Lightweight Crocs, flip-flops, or sandals are easy to strap to your pack. Change into these after running to allow your skin time to heal from the moisture.

Insoles and Beyond is a family-owned small business based in North Carolina. They want to help you be comfortable, avoid injury, and reduce any pain you are experiencing. Their insole line includes a wide variety of insoles from manufacturers including, Birkenstock, currexSole, New Balance, Powerstep, Sof Sole, and Sole. Whether you are looking for orthotics for plantar fasciitis pain, arch support inserts for comfort, or insoles for running shoes and other sports performance, you can find them at Insoles and Beyond. Within each company’s line are a variety of insoles and sizes. You can look for insoles by company name, foot type, activity, pain/condition, and shoe type. They also carry compression wear from CEP compression and Mediven, and offer ankle braces, knee braces and splints as well.
Because many athletes don’t understand insoles, I asked Stacey some questions about insoles. I think the questions will help you when you need insoles, or if you are unsure why you should replace the standard “sock liner” that came with your shoes. For years, I have told people that generally speaking, the stock sock liners shipped in shoes offer little support and are of little help. Many are simply thin pieces of foam or cardboard. Read on to learn about insoles. Then check out Insoles and Beyond’s website.
I’ve run for years and always used the regular insoles that come with shoes. Why should I consider a replacement pair of insoles? Most running shoes (expensive and inexpensive alike) use very simple and cheap foam insoles despite the tons of science that goes into making the rest of the shoe. Many runners will spend $100 to $200 on a pair of running shoes based on the materials and technology used to make them but then leave in the relatively generic insoles that come with the shoes. It makes sense that shoe manufacturers don’t invest much in the insoles – everyone’s foot is different. Shoe manufactures leave it to the consumer to purchase the appropriate insoles for their specific foot needs – high arches, low arches, overpronation, etc. Additionally, some people want more cushioning than others. Some want more support than others. Personally, the first thing I do when I buy a pair of shoes is rip out the “sock liner” and put in a pair of my favorite insoles.
There’s a whole bunch of replacement insoles to choose from, how can I make an intelligent choice? Our website has some good information on the various types of insoles and categories (collections) to help you find the insole that is appropriate for you. So, that’s a good starting place. However, within the categories (insoles for plantar fasciitis, insoles for running, insoles for hiking, etc.) there may still be questions. At that point, I’d suggest calling us or sending us an email to discuss things further.
Are certain insoles better than others for minimalist shoes and zero-drop shoes? Absolutely. Lower profile/volume insoles are best for minimalist shoes. Sole’s ThinSport and currexSole’s RunPros are both low volume options. The ThinSport has the same arch support as Sole’s Response and Ultra, but with less cushioning. The currexSole RunPros pack a lot of cushioning and less arch support (allowing for a more natural feel). Most insoles are neutral in terms of drop – they can be worn in zero-drop shoes.
How long do these insoles last? That depends. Many manufacturers recommend that you replace the insoles as often as you replace your shoes. Generally most running shoes should be replaced at 500 miles. I find that the BirkoSport by Birkenstock last pretty long – I’ve used them through four or five shoe replacements. Sole, New Balance, and Powerstep insoles tend to last a while (3 or 4 changes). Birkenstock and Sole both mold to your feet the longer you wear them. SofSole tends to only last one or two changes, but they are also less expensive. Generally speaking the more cushioned the insoles and the more activity they are subjected to, the more frequently you’ll need to replace them.
What’s the difference between inexpensive insoles and the more expensive ones? I believe you can get a really good pair of insoles in the $25 to $65 range. Custom insoles can run hundreds of dollars and many customers who’ve had custom insoles have shared with us that the $40 insoles they got from us were just as effective as the $400 custom pair they got from their doctor. The cheap insoles ($10 to $20 insoles at the drugstore) tend to not be much better than the insoles that come in the shoes to begin with. Among the insoles we offer, the materials used and the overall durability of the insoles set inexpensive and expensive insoles apart. I find that the more expensive the insoles, the longer they tend to last. Conversely, the less expensive insoles last a shorter period of time. Materials like carbon fiber, cork latex, tend to be more expensive and durable than gel insoles.
I cross-train and ride bikes too. Are there insoles made for biking shoes? There are definitely insoles specifically made for biking shoes. You can, however, use general purpose or running shoe insoles for biking shoes as well. The trick is to make sure that the insoles are low volume (since most biking shoes will not accommodate thick insoles) and that they have good cushioning in the ball of the foot (the part that is in contact with the bike pedal the most). Something like the currexSole RunPro can easily go from your cycling shoes to your running shoes if you are cross-training.
You may be asking why you would order insoles from Insoles and Beyond. Yes, you can find insoles in the foot care section of your local drugstore, sporting goods store, and running store. But will they be the right ones for your feet? Check out their lines of insoles and if you have questions, give them a call. On the right side of their page, is a 10% coupon and they offer free shipping in the U.S.
Disclosure: I have no financial involvement in Insoles and Beyond.
Back in the early 80’s I bought my first pair of running shoes. I went for New Balance, and they coast an amazing $45.00. There were the big names at that point: Adidas, Asics, Brooks, Nike, New Balance, Puma, and Reebok.
That was then. This is now. Shoe companies galore.
- Hoka One One
- New Balance
- Newton Running
- Pearl Izumi
- Topo Athletic
- Under Amour
- Vibram FiveFingers
Twenty nine shoe companies! I faint that amazing and overwhelming. There may be more I missed.
Then of course, each of these companies have different versions of shoes, typically road and trail. Then different types of control and support features. Then “regular” shoes versus minimalist shoes. And zero-drop shoes.
I went to one online website of a well-known company that sells many different shoes and some of the shoes manufactures had 16 or 18 different shoes models to choose from.
Companies that were known for their hiking boots and shoes now make running road and trail shoes. An underwear company makes shoes. It’s a hot market and everyone want a piece of the pie.
What’s a runner to do when they need new shoes? In my mind, there are three answers:
- First, visit your friendly neighborhood running store. And no, I don’t mean Big 5. I mean a running store with people who actually run, know shoes, and can make recommendation based on your form and gait, foot strike, shoe history, and even injury history.
- Secondly, use the services of a reputable online running shoe company. They typically offer call-in support to help you select the right shoes or a chat pop-up box to ask a sale person questions to determine the right shoes. Some even have online shoe buying guides.
- Thirdly, take a chance and just buy or order a pair of shoes on your own.
I recommend the options in the order presented. The running shoe marketplace is too crowded to make an intelligent choice any other way.

A few weeks ago I was interviewed by Scott Warr and Don Freeman from Trail Runner Nation. I was honored they asked me and we had fun doing the interview. The subject? What else but feet!
You can listen to the interview on their website, download the MP3 file, or better yet, subscribe to their podcast series through iTunes. Here’s the link to their webpage: FEET – Injury Prevention and Treatment with John Vonhof.
Here’s what they wrote on their website:
One of your most important tools as a runner is your feet. You need to take care of them or your training/race may be foiled. John Vonhof literally wrote the book on how to take care of your feet: Fixing Your Feet. This book is now in the FIFTH edition! John joins The Nation to discuss the basic principles of foot care:
- How you can have healthy & happy feet
- Blister prevention and treatment
- What to keep in a foot care kit
- Taping your feet
The interview is 62 minutes in length, but my interview starts about five minutes in. Enjoy the interview and then subscribe to Trail Runner Nation’s podcast.
Thanks Scott and Don for giving me the opportunity to share a bit of my passion for feet on your podcast.
How specialized can shoes become? Last year I watched many runners at the Jungle Marathon Amazon struggle with waterlogged shoes. The race went through rivers and swamps, dirt roads, sand on beaches and in the jungle, and through all kinds of rocks, roots, and other jungle junk. I remember one racer whose waterlogged Hoka’s seemed to each weigh three pounds after a day going through water, sand, and jungle. I saw shoes after shoes that were filled with sand and dirt, and were also waterlogged. This makes one’s race harder as you have to lift that weight with every step.
I have run races where my shoes were wet from stream or river crossings, or rain, or from puddles. Now Reebok has introduced their All-Terrain Series shoe as a solution to the problem with water. The shoes were designed to help runners in the Spartan Race Series of obstacle courses.
The Rebook All-Terrain Series Shoe
The Reebok All-Terrain Series shoe is a new shoe made for the popular obstacle races popping up worldwide – but I think they’ll be valuable in any race or event where water is a problem and traction is important. It’s named after the ever-popular Spartan Race Series and was designed and engineered in cooperation with the Reebok Spartan Race community. An important feature is the mesh H2O Drain ports that drain water quickly through the upper and midsole. The Super model has four drain holes on each side. The Sprint model has small drain holes all over the mesh upper.
The shoe has an outsole with square indented lugs and mid-foot teeth offering superior traction to shed mud. There are even lugs on the front toe of the shoe. The shoe is lightweight and breathable, with a rubberized tongue that will not absorb water and has holes to help expel water. Under the foot is a RockGuard plate to provide protection from rocks and other hard or sharp objects. The upper is made of DuraGrip for durability and ION Mask-fabric to repel mud and water. The shoe’s colors are vivid and bright.
There are two models, an All-Terrain Super and an All-Terrain Sprint. The Super is made for longer distance races and is engineered with more cushioning and stability. The Sprint is made for shorter distance races with a light-weight midsole and a low drop.
This is a serious shoe for obstacle course racers or events were water is a problem. It’s a shoe that can handle any abuse a Spartan Race can give it so you are unstoppable on any course – provided your legs and body don’t quit. I read reviews of Spartan racers who had tested the shoe and all swore by the H2O Drain ports. Having spent a week last October in the Amazon, I saw what wet shoes do to a runner’s feet. I think these would be great in the Amazon or any event with lots of water.
The Reebok All-Terrain Super retails for $119.98 while the Sprint is $109.98. Reebok says they should be in stores the end of April. They are also available through the Reebok website. I’m told they run a bit small so it is recommended to go up a half size. Reebok also offers the option to design your own shoe with a variety of colors for the upper, midsole, laces, tongue, and more. Here’s the link to check out the Reebok All-Terrain Series shoes.
Of course, remember to try any shoe for a while before committing to wear it in a race or long distance run/hike. Make sure the fit works on your feet. Make sure any shoes you buy for a specific event will hold up through whatever it throws at your feet.
The Spartan Race Series
The Spartan Race Series is an international obstacle racing series with three levels of courses: a 3-mile Sprint, an 8-mile Super and a 10-12 mile Beast. You will run, jump and crawl your way over a dozen or more obstacles. Courses are uniquely designed to test your mental and emotional fitness and push you past your limits. Race as an individual, as a part of a team or both!
Choose your Spartan Race here. There are races in many states, as well as Canada, England, France, and 11 other countries. Spartan has offered a discount to my readers interested in trying a Spartan Race. You can get 15% off any Spartan Race in the continental U.S.

Occasionally I see runner’s shoes that have wear holes in the material in the heel counter. This picture from Dan shows his shoes with holes to the outside of center on both heels. I emailed the following suggestion.
I’d try an ENGO Back of Heel Patch. They are made to shape to the curve of the back of the heel counter. Put them in when the shoe is dry. Rub them a bit in a curving motion to help them form to the shape of the shoe. Then peel off the paper backing and apply from the center outwards to the sides. Rub well so they adhere to the shoe’s material. You could also try the large ovals if the hole is small. The blue ENGO patches are very slick and can take a lot of wear. Once the blue wears down to expose white, replace the patch. Sometimes the holes are on the sides of the heel.
Last summer at Western States, I had a runner whose shoe was rubbing her heel raw. You can see from the image that she has a prominent heel bump. This, of course, contributed to her problem. This is the kind of problem one needs to plan for before it becomes a major issue – especially at the event the magnitude of Western States.
We decided to cut a notch out of the outside of her shoe’s heel. This allowed the back of the shoe to spread apart for her large heel bump. Then I applied an ENGO Back of the Heel Patch to the inside of the shoe’s heel counter. This provided some protection to her heel bump.
The large ENGO ovals can also be used when there is a small area to be covered.
I have been a fan of ENGO Blister Prevention Patches since I first discovered them years ago. The ovals are perfect for the common areas at the side of the heel where blisters form at the junction of insole and heel counter. The large rectangles are great to put on insoles underneath the ball of the foot, another common problem area.
Check out the ENGO website for more information. ENGO products are available through Zombierunner. If you are in Australia or New Zealand, ENGO products are available through Rebecca Rushton’s Blister Prevention website.
Disclosure: Tamarack Habilitation Technologies supplies me with ENGO Patches as I need them for races.
