I have had much foot surgery, and find that SPERRy(the boat shoe company)makes a WONDERFUL flip flop.... has a good sole, some styles have a round tube over the big toe. , and a good arch. also, SPEEDO is a good brand.thye have a cloth piece between the toes. Both are pricey, in the 30 or 35 dollar range, but can wear them all day long and no back aches either....... also, NO flip flop sound when walking....... jacie
