I love how technology continues to push the limits in sock construction. The companies below offer unique sock design that shows how companies are making products that stand out in a crowded field. Here are four interesting sock companies worth check out.
Ellsworth V-Channel socks have vapor channels to carry sweat vapors through the channels and off the foot – keeping the foot drier. The channels run from the toes to the heels.
Farm to Feet has developed their Blackburg Water Sock with a combination of nylons and elastic yarns in a unique design that allows water to drain quickly, dries quickly, and provides UIV protection. PTFE-coated nylon fibers create a frictionless feel.
Sensoria Fitness smart Socks harness new technology by embedding electronic threads and textile sensors, and pairs these with thin anklets on the tops of the socks, These are paired with a Smartphone app to capture step count, cadence, and foot strike forces. The full system also has a heart rate monitor for full data capture and a virtual coach in your ear.
ArmaSkin anti-blister socks offer a layer of dermal protection with their socks, engineered for extreme endurance athletes. These are thin but tight fitting and are worn under your normal socks. The Si Fusion coating sticks to the skin and prevents any friction generation next to the skin while giving a dermal like layer of skin protection. In addition, the Si Fusion hydrophobic inner pushes moisture to the outer layer and is bacteria static so the socks can be worn for long periods of time. ArmaSkin’s smooth outer fabric reduces friction by allowing the outer sock and shoe to move harmlessly over the foot – preventing blisters. They recommend not using any lubricant inside their socks – other than a small dab between toes as needed. The socks are made in Australia, making them harder to find, but their positive features make the search worthwhile.
When you purchase socks, spend a moment reading the washing instructions. With most performance socks, you should not use bleach and fabric softeners as these may break down the fibers.
Check out the above socks and buy a pair or two. As always, don’t try them for the first time in a race.

This summer will see the release of the 6th edition of Fixing Your Feet: Injury Prevention and Treatment for Athletes. The exact date is still up in the air, but I’d expect it sometime in late July or early August.
The 5th edition was released in February 2011 and it was due for an update. Nothing in foot care remains static. New products and techniques are constantly being identied.
The new edition will be fully updated with new material, websites, new foot care products and product information, and new techniques and learning’s in footcare. I have been working with the publisher since last summer in talking about ways of improving the content. Every paragraph on every page has been evaluated to determine whether the content could be made clearer, or whether it is dated and needs to be removed. Much of the content has been expanded to provide more benefit.
The sixth edition has an important new chapter, Blister Prevention – A New Paradigm. It contains new information about blister formation and introduces the concept of shear, which in turn, changes the way we look at blister prevention and treatment. This chapter itself is worth the cost of the book.
It’s available for preorder at Amazon with their pre-order price guarantee. You can order now and if the Amazon.com price decreases between your order time and the end of the day of the release date, you’ll receive the lowest price. Here’s the link: Pre-order Fixing Your Feet, 6th edition on Amazon.
The cover is still being worked on and will likely change.

I have known Terri Schneider for a long time. She did triathlons, moved up to focus on Ironman’s, then discovered adventure racing. When I heard about her new book, I knew I had to interview her. Her just released book, Dirty Inspirations, tells the stories of her “lessons from the trenches of extreme endurance sports” – the subtitle of the book.
From the back cover, we read, “By choosing to walk the path of more resistance, we come to a better understanding of ourselves and our potential for physical, mental, and emotional growth. And nowhere is this better represented than in the crucible of extreme endurance sports, where athletes are truly pushed beyond the bounds of what seems possible. Seen through the eyes of one of the most diversely experienced female athletes on the planet, the stories in Dirty Inspirations showcase discomfort as virtue, and demonstrate the truly indomitable nature of the human spirit.”
Chapters in Dirty Inspirations take readers into Ironman and adventure races and ultramarathons in Utah, Australia, California, Costa Rica, Malaysia, Tibet and Nepal, New Zealand, Egypt, China, Argentina, Alaska, and Ecuador. Terri raced in many countries, with huge awe-inspiring challenges, and unforgettable memories.
Along the way, she also learned a lot about her feet and how to do foot care. In this unique audio interview, I talk to Terri about the races, foot care secrets, and a lot more. It’s about 23 minutes in length.
Along the way, Terri learned a lot about herself as an athlete and a person. You and I may not have the opportunities to do the races she did, but we can live them through her stories.
For an in-depth interview with Terri about the book and how she wrote it, check out my Writers & Authors on Fire podcast where I interview her for an hour about the writing process.

This second version of a toe separator is a more complicated to make and apply. It uses a large or small ENGO oval, depending on the size of the toes. The idea is to pinch the patch into an upside down T where the base of the T goes between the two problem toes. The patch is stuck to your insole in a position where it keeps the two toes apart. The slippery surface of the ENGO patch will prevent rubbing and the upward base of the upside down T will keep one toe from going under the other toe.
How to Make Your Own Toe Separator # 2
Using a utility knife, score two cuts, about one inch apart on the backside of the patch. Make them only deep enough to cut through the paper backing – do not cut through the patch itself. Try to have the one-inch wide space in the middle of the patch. Make the width of the cuts wide enough so the folded separator will be tall enough to match the height of the toes it will go between. This is important – a separator used between middle toes will have to be taller than ones used for pinky toes. Men’s toes may also require taller separators. Using the tip of the knife, remove the one-inch strip. Fold the patch in half so the sticky sides match to each other. The two end of the cut backing should meet in the middle. You can now open the two ends and cut the patch into the needed shape based on where the patch will go on the insole and the length of your toes.
Separator # 2 Height and Length
Separators for pinky toes need to be shorter in height and length than ones for the middle toes. You may have to make more than one separator based on the size you need to find the right fit.
How to Use the Separator # 2
To use the separator in your shoe, remove the insole for the foot with the overlapping toes. The smoother the insole the better the patch will stick. Clean the surface of the insole of all lint, dust or other things that could interfere with the patch adhering. Make sure the insoles are dry. Put the insole on the floor and stand on it so your foot falls into any indentations. Usually, an insole will have indentations under the heel, ball of the foot, and some of the toes. Using a pen, make a mark between the two affected toes. Put on a pair of Injinji socks and make sure the marking is still in the right place.
Once the placement has been confirmed, with sock on, place the separator between the two toes to make sure it fits. The best way to do this is with your foot on the insole. The height should come up to the top of the toes with sock on. If the height is too high, trim it with a scissors. If it’s too low, make another separator where the pinched section is higher.
The length needs to be long enough to cover the body of the toe – without hitting the crease between the toes. If the separator touches the crease, it could rub and cause problems, especially if the foot moves forward in the shoe. If it’s too long, trim it with a scissors.
Once the fit has been checked, you can place the separator on the insole. Line it up so the upward part is in the correct place. Then remove the protective backing to expose the adhesive and place the patch on the insole with the upward part over the line on the insole. Rub the separator to make sure it is firmly secured to the insole. Use a scissors to trim any part that extends over the sides of the insole. Use a blow dryer for a few
If the patch does not stick, you probably have an insole with a surface that is not smooth enough or too soft with too much fabric that does not allow the adhesive to hold. In this case, you may want to try another insole with a better surface. They can be peeled off the insole if they are placed wrong, but will probably not stick as well if you try to reattach them. The patches will not stick to a wet insole. For easier removal, use a blow dryer or heat gun to heat the patch.
If the Separator # 2 is Too Weak
It’s possible that the pinched section of the ENGO patch will be too weak or thin to keep the toe from going under the next toe. If you can tell the toe is going under, here’s an idea to make it stronger. Take another ENGO Patch and cut a strip the width of the top of the separator, remove the adhesive backing, and pinch it over the existing separator so it reinforces the upward part of the separator and extends onto the base. This will strengthen the part between the toes and make it stiffer and better able to keep one toe from going under the other.

This is part one of a two-part blog post.
Over the past few years, I have seen many athletes with a common toe problem – overlapping toes. Some people may call then underlapping toes or call them some other name. When a pinky toe goes under the 4th toe, both toes can be negatively affected. Skin is pinched. Hot spots and then blisters form. Often callus develops as the skin is constantly under pressure from the overlapping toe.
While most common to the 4th toe and pinky toe, overlapping toes can affect any two toes. This is not necessarily a problem limited to running shoes or hiking footwear. It can happen in everyday footwear too. The cause of over-lapping is unknown. Many experts suspect that they are caused by an imbalance in the small muscles of the foot.
There are some easy solutions, which may or may not help, because toes are different. You can switch to Injinji toe socks, giving each toe it’s own little sock and some degree of protection. You can cut out a portion of the insole under the toe that goes under the other toe, giving the toe some extra space. Another option is to tape around the toe or toes to give some protection too.
This is an idea to help runners, adventure racers, and hikers with the problem of overlapping toes. You will need Injinji toe socks, ENGO Blister Prevention Patches (large ovals), and removable insoles. There are two types of separators you can make. This post will cover the first of the two.
Toe Separator Number 1
I use an ENGO Blister Prevention Patch as the toe separators. They make a small and large oval, but I like the large because of its size.
The first toe separator is easy to make and use – and it uses one large ENGO patch. Take a scissors and cut a long oval into a strip, about ¾ inch wide and 1¾ inches long. If you are cutting this for a middle toe or for large toes, it may have to be 1 to 1 ¼ inches wide and a bit longer. Round all corners. Cut one of the remaining sections into a small strip, ¼ inch wide and 1¼ inch long. Take the large oval and remove half the backing from one end. Wearing Injinji socks, put the large oval between the two affected toes. Put the end of the large oval with the exposed adhesive over the toe next to the toe that goes under it. The blue side will go from the top of one toe, run between the toes, and under the toe that normally goes under the other one. What you have is an S shaped patch from the top of one toe, between them, and then under the next toe. Take the small strip and remove the backing, and put one end of the adhesive on the white backing that is underneath the toe at the bottom of the S. The other end of the strip can be stuck onto the top of that toes sock. The small strip is needed to hold the bottom of the S under the toe when you put your foot in your shoe. The S shaped patch will keep the toes apart. Obviously, these are single use. If the patch seems too weak, use two strips to make the S patch stronger.

Today’s post will cover a great way to prevent blisters using ENGO Blister Prevention Patches. It’s a repeat of a post from mid-2013.
Tamarack Habilitation Technologies is well known for providing healthcare professionals and clients with innovative, value-added orthotic-prosthetic componentry and materials. Their ShearBan product is similar to the ENGO Blister Prevention Patches reviewed in this article. ShearBan is used in the orthopaedic and prosthetic industry on prostheses at amputation stump sites to reduce the incidence of skin breakdown.
ENGO in Footwear
Introduced in 2004, ENGO Blister Prevention Patches have radically redefined the way hot spots, blisters and calluses are treated. As a preventative measure, ENGO patches provide peace-of-mind that blisters won’t become a painful, debilitating problem. If a blister has already formed, applying patches to footwear, corresponding to the blistered area eliminates painful irritation and further skin damage, allowing continued activity. Friction forces are reduced by more than 50% when you apply an ENGO Patch to your footwear.
The patches are made from an ultra-thin Polytetrafluoroethylene (PTFE) film and are 0.015 inches total thickness – a very slippery surface. They are very durable, lasting four to six weeks in most applications. The aggressively sticky patch peels away from the backing and is applied to dry shoes or boots. The PTFE ENGO Patch reduces the ‘stickiness’ between the shoe and sock so they can glide over one another. The foot, inside the sock, glides over the patch shear distortion and friction are reduced, and blisters can be averted, in spite of pressure.
Avid runners, hikers and sports players rely on their feet to reach performance goals; from day hikes to ultra marathons. But quality footwear and socks alone don’t eliminate the skin trauma your feet can experience from repetitive rubbing — building friction forces to levels that cause hot spots, blisters and calluses. While I use these patches in runners’ footwear at races, they can also be used in ordinary every day shoes to reduce calluses.
Similar to Tamarack’s ShearBan material, ENGO patches are applied directly to footwear and equipment, not to the skin. Outcomes of this unique application include ease of use, long-lasting and guaranteed friction relief.
ENGO Patches are made in several sizes and types:
- A large oval – 2 ¾ x 1 ¾
- A small oval – 2 x 1 ½
- A rectangle – 3 ¾ x 2 ¾
- Back of the heel patch – 3 ¾ x 1 ¾
- A cushion heel wrap – 3 ¾ x 1 ½
When I work a race I always have a bag with different sizes of ENGO patches. I have applied the ovals and rectangles and the back of the heel patches. The patches are applied to the shoes and insoles – not to your skin. This means wherever you are going to apply a patch has to be dry. My advice is to apply patches before your race when your shoes are dry. I have used them inside the shoes in the sides, in the heels, and on the insoles.
Typical problem areas in footwear are under the heel and forefoot, and at the side of the heel. An oval patch can be applied to overlap the side of the heel counter and the insole as seen is the photo. I often use a rectangle or large oval under the ball of the foot or an oval under the heel – applied directly to the insole. The patches are useful over stitching or seams in footwear that are rubbing the wearer. If necessary, a patch can be cut to shape for where it will be applied.
The patches will reduce shear and friction; provide relief from hot spot and blister pain, and can be used in any type of insole or orthotic and footwear, from sandals to running shoes, and any type of hiking or ski boot.
I like ENGO patches because they work. The patch is thin and does not alter the fit of the shoe. When properly applied to dry footwear, they stick.
Rebecca Rushton, a podiatrist in Australia, strongly recommends ENGO Patches. She discovered the patches after getting blisters herself and now represents ENGO in Australia. She has written several free reports on blister prevention available on her website, Blister Prevention.
If you are unclear about shear and blister formation, here’s a link to my article An Introduction to Shear and Blister Formation.
The Technical Stuff
JM Carlson, in a 2009 report wrote, “The measurement of friction is the ‘coefficient of friction’. The coefficient of friction (COF) is a number that represents this slipperiness or stickiness between two surfaces and is generally below 1.0. Within the shoe, the COF between the foot, socks and insole can range from 0.5 – 0.9. In contrast the COF between a sock and a polished floor is around 0.2.” Tests have shown PTFE patches to reduce the coefficient of friction (COF) in the shoe by up to 80%. The COF is in approximately 0.16, which is significantly lower than all other in-shoe materials. Importantly, the low COF is maintained even in most and wet conditions inside the shoe.

Rebecca Rushton is a podiatrist from down-under in Australia. She has championed the important of blister prevention and I have shared about her in past blog posts. Her website, BlisterPrevention.com.au is a wealth of information on the subject.
In an effort to resolver her own blister problems, Rebecca has investigated podiatry and sport publications, diabetic foot disease and prosthetic limb skin management, the field of tribology (the study of friction and wear), and military research. These have led her to write a number of publications about blister management, and continually address it in her blog.
Her latest work is a book and ebook, The Blister Prone Athlete’s Guide to Preventing Foot Blisters: Insider Tips to Take You From Blister Victim to Champion. These are available through Amazon – and for a limited time, the ebook version is available for FREE through Amazon’s Kindle. Here’s the link for the free ebook. Get it soon because after five days, it reverts back to normal prices. You can also get a print copy of the book to have in your foot care kit and share with your crews.
The 75-page book discusses blister formation and then tackles the causes and prevention of blisters on the most common areas of the foot: heels, the arch, the ball of the foot, and toes. The content is easy to understand and follow.
Rebecca is a friend and I highly recommend her book. I’d also suggest visiting her BlisterPrevention.com.au website and subscribing to her email updates.

After years without an expedition length adventure race in northern California, the Primal Quest Adventure Race returned this past August. Even though there were openings for 20 four-person teams, only 11 teams toed the starting line in South Lake Tahoe.
For those unfamiliar with adventure racing, races generally consist of a mix of disciplines: trekking, mountain biking, orienteering, white waters, rafting, kayaking, and ascending and rappelling. Some events have caving and other exotic disciplines.
This year’s race stated with a downhill run to kayaks on the shore of Lake Tahoe, after which they paddled north, and then took off on mountain bikes for a long ride. Unfortunately, much of the 80+ miles turned into a hike-a-bike. Then at Kirkwood, they took off on foot for a long trek / orienteering section. For some teams, this section took hours longer then expected.
I was at TA3 (transition area) and we expected the first team early Friday morning, but in fact they arrived almost 24 hours behind schedule. The rest of the teams were spacer further and further apart as time progressed.
My point is that many of the racers had been on their feet for more than two and three days by the time they reached us. Then teams went back on their bikes, into kayaks, and into another long trek. Some teams were short-coursed – taken ahead on the course
Fast forward to TA6, a day and a half later and teams are still racing. Some of the racer who have done the full course to this point have had little time to rest and their feet are extremely sore to the point of being very painful. They may also have some degree of maceration going on too.
One such racer, Thomas, asked me to look at his feet. There were no blisters on the balls of his feet, just very soft and tender skin – very sore with some maceration. I told him I could help.
I cleaned his feet and allowed them to air dry. I applied Tincture of Benzoin Compound to the skin from mid-foot upwards to the base of the toes. Over this I place a piece of soft, 1/8 inch thick Hapla Fleecy Web (adhesive felt), cut to follow the shape of foot at the base of the toes, square at the bottom, and curving up a bit on each side of the foot. At the base of the felt, mid-foot, I placed a strip of Leukotape to help hold down the bottom edge of the felt. Benzoin was used under the tape and edges were rounded. The last touch was two figure 8’s, cut from HypaFix cotton tape, placed between the 1st and 2nd toes and the 3rd and 4th toes, with the bottom of the 8 under the foot and the top of the 8 on top of the foot. This anchors the forward edge of the felt against the skin and keeps it from rolling, especially on downhills. Each figure 8 is about three to four inches in length and the tape is two inches in width.
I received a report later in the race that the patch job had held. After the race ended, Thomas let me know the patch had helped his race.
The adhesive felt helps pad the forefoot and provide cushioning to the sensitive tissues, and can help relieve pain and discomfort from maceration. This is not moleskin, or a version of moleskin. It’s a thicker product and much softer. The felt can be found in 1/8 and 1/4 inch thicknesses. In the Amazon we used fleecy web that is 1/8 inches thick. In the Amazon Jungle Marathon I used the patch job many times on macerated feet – after drying the skin as much as possible.
Medco Athletics sells adhesive felt in a variety if thickness and lengths. You can search on “adhesive felt” or for a specific product I have used, “Fleecy Web.” To give you an estimate on pricing, four Hapla Fleecy Web 9” x 16”, x 1/8 thick sheets sells at Medco for about $26.00. The Hapla Feecy Web is 100% cotton and is latex free.
It also works well for padding around blisters, bunions, heel bumps, and more. Because it is thicker than tape, I would use Benzoin to help it stick better and consider adding extra tape as I described above.
