VFF-Vibrim Five Fingers, toe shoes.
Please, let us know how those sandals workout for you. It is a hassle to have to tie those shoes, but once on they feel so very bare. My rubber soles didn't work out for me and get used. I probably have another 4980 miles on the warrantee. I wear my homemade huaraches with thin leather soles and leather straps.
If I can train myself to walk more properly, I'll give the rubbers another chance. Around the house, when the ground gets too hot, I go for my slip on while standing up Chaco flip flops.
