Been doing the barefoot running seriously for the last month. Worked up from 1/2-mile, 3/4-mile, to the mile/1.25 miles I'm doing every other day (or two) now. Great. But I keep getting some rawness on my (mostly) right foot. It'll show up just behind the big toe as well as on that ball of my foot where the fifth metatarsal is. The feeling will be like I'm about to get a blister, maybe if I pushed myself another 1/2 to 1 mile I'm certain a blister would be there. But as it is, no real blister, pain goes away in the next day, and I'll go out on the second day after. On occasion, the more deadish skin will try to peel away. Sure, lift my feet more. Got it and I'll keep working on it. But is it really a lifting issue or just the soles adapting to running? Surface I run almost exclusively is a poured concrete sidewalk with varying degrees of roughness. Not as bad as that chip-n-seal stuff that makes up the street, but I feel like its a good starter surface to build up the form, soles, and miles. Any advice? Am I going to make it to a barefoot runner?
