The real unique and revolutionary feature of the teva proton is it's curved/rounded edges like your foot!Notice the curve of the heel and outer edge your barefoot.The teva feels alot like running barefoot.The thin layer of rubber provides just enough protection from rocks,glass,etc.
At 35 bucks a pair(At Rei) you can't go wrong.

Beach shoes -- nylon uppers -- rubber soles -- $6 -- Walmart.
