Last year I stopped wearing shoes, in the most common sense. Crocs, Teva sandals, shoes of no particular form, have been my experiment. Yesterday I hiked in last years hiking shoes and damn, my left foot was cramped by the time I made 8 miles. (I think my feet have spread out a bit) Frankly this isn't going to work for me. So here are my current thoughts, in visual form.
Above you see a pair of home made sandals that use a vibram sole that seems to be pretty grippy. You see two different ways to attach them to my feet. I don't know which would be better. The next idea is to use moccasins.
