I started running barefoot back in May and I've been overall enjoying it, but I have a few questions for you experienced barefoot runners. 1. How do you deal with hot surfaces? So far the only solution I've found is to run on surfaces that are not heated so much by the sun. I've made sure my cadence is around 180-190 so my feet don't stay on the ground too much, but my feet are still getting a little burned. 2. How do you prevent and treat split calluses? My family seems to have a genetic predisposition towards dry, split calluses in our feet. I have used O'keefe's Healthy Feet on the cracks and it has helped, but I'm wondering what other solutions are out there. Thanks!
