I'm a new barefoot runner having only about 100 miles unshod so far. I ran a 6.7 mile trail run with a group form a local running store this morning. This was not my longest distance or fastest pace but the trail was not very friendly to the newly bare foot. I felt great while running and enjoyed the looks of amazement mixed with disgust from the very gracious and friendly group. For the first time I developed large blisters on the balls of my feet below the big toes and can barely walk on them. What should I do to get back on my feet ASAP? Thanks
