im confused what you mean by duribility, if you mean can you run distance races in them, then yes, i regularly run 20+ miles in barefoot shoes, a blog i read is written by a man who runs ultra's upto 100miles and wears barefoot shoes only.
by how long they last? depends on the shoe, the hattori to me felt like they wouldnt last long, a few 100 miles at most, but ive never ran in them so i dont know, but something like the vbram soled merrell barefoot range will last 1000 miles (from experience)
