Last month I was at my local REI store to conduct a clinic on foot care. At the same time, they held a footwear festival, which had eight footwear companies represented.
I noted something about some of the shoes that is valuable to know if you are shopping for shoes. Specifically, the materials of the shoe’s upper.
I have two photos to share with you. The shoes in these photos are made by Salomon. In fair disclosure, I have several pairs of Salomon shoes that I received as swag for working medical at races. I find they are well made and are easy to fit to my feet.
The first photo shows a shoe that is typical of many shoes today – by most of the companies. The shoe’s upper is made with a mesh material. Whether it is one or two, or even more layers is not important. It’s mesh.
Wearing shoes with a mesh upper will generally help keep your feet cooler. But the mesh allows minute particles of sand and dirt to get inside, onto and into your socks, and on your skin. Those particles can cause friction and over time can cause hot spots and then blisters to develop. Yes you can wear gaiters, but the usual gaiter design covers only part of the front of the shoe’s upper. Stuff still gets inside. The alternative gaiter is a design that covers the full shoes, from the outer sole up over the ankle. A few months ago, I did a review of a gaiter that covers the whole shoe. Here’s the link.

The second photo shoes a different shoe, also made by Salomon, that has an upper made with a non-mesh material. This upper will keep sand and dirt out of the shoe. A gaiter with this shoe will be useful if you are running in a sandy, dusty, or dirty course, where you would likely get stuff into your shoe through the top of the shoe.
To be truthful, I feel strongly that trail runners should wear gaiters regardless of what shoes they wear. Gaiters are good proven equipment.
If you have a race or event on your summer calendar that involves lots of sand and loose dirt, keep the material of your shoes in mind when planning. Something as simple as a non-mesh upper can save your feet.
