These are just what I needed, chunky stiff sandals. They're secure enough that you can loosen the straps a bit and not worry about them slipping off, and they don't have the problem that all the other pairs I've worn have of not getting slippery. under your feet when you enter the water. The soles are already wearing out from the sand, but this is inevitable and they will eventually wear out as the tread wears. It was a good buy.
