While these don't have some fancy logo on them, these sandals are very functional for my needs.  I use them so I don't catch athletes feet at my fitness center pool and showers.  They also make sure you don't slip and fall poolside and in the shower room. I've forgotten to wear them a couple of times and almost cracked my skull.

They're a bargain for what they do.
