Summer is officially here—and many involved in walking, running, hiking, adventure racing, doing a triathlon, or any other sport where shoes and socks are worn, will have damp or wet feet.
I am urging you to go to your sock drawer and throw out any socks that are not moisture wicking—or at least put them aside for the summer. Usually these are cotton. Visit your friendly outdoor store, running store, or camping store, and get a few pairs of synthetic blend or wool socks which will take the moisture away from your skin and move it to the outside of your socks. Wet feet, from perspiration or water (from any source), will make your feet more prone to blisters. Dry feet, on the other hand, have less friction, and therefore, are less prone to blisters.
If you find your feet are getting hot spots or blisters, this is the first thing I would check. Of course, humidity can also contribute to dampness. Socks will only help so much. Your feet will be somewhat clammy, but, you want to avoid overly damp and wet feet. Damp and wet socks that hold moisture against the skin will lead to skin problems and blisters – so do yourself a favor and wear moisture wicking socks. Almost every quality store carries several brands of these socks now days. You should have no trouble finding them.
