I started wearing these when I walked the Breast Cancer 3 Day. I have a "shy" toe that hides beneath the toe next to it. It would rub and after each practice walk, I would end up with blisters. I switched to the Injini and haven't had a problem since. Recently I was on a vacation in Florida, just walking a few miles and ended up with 4 hot spots. I switched back to my Injini socks and not a problem. Now, all I will wear are the Injini socks
