I just came in from walking the dog around our neighborhood, which I've been doing barefoot since winter ended. I've always liked walking barefoot.
After my feet got torn up by some sandals that I was wearing on a long backpacking trip, I decided to toughen my feet up, so that wouldn't happen again. For most of the next year, I went barefoot. This was in college, so it was more socially acceptable than it normally would be.
Barefoot walking is excellent for developing the muscles in your feet and lower legs. Shoes are essentially soft casts, after all.
Do any of you like going barefoot?
If so, what do you like about it?
