I think hot spots are due more to the shoe, and the way it fits or should I say, in the way they DON'T fit. But perhaps even moreso, they are due to the the socks you are wearing. I have been wearing some older socks lately that seem to be better wicking and have not had hot spots in a long time. Unfortunately the socks are so old - just regular white tennis type socks - that I don't know what brand they are or anything.
