I notice you tend to get a lot of blisters when you run barefoot. Is this a result of your technique or lack of padding and callous on your feet?
I am still learning but I believe my blister problem is caused by my form. On my run last night, I worked on shortening my stride, quickening my cadence and pulling my feet straight up to avoid friction and they felt way better than they usually do at the end of a barefoot run. I think the blisters will decrease as my form improves.
