These were a Chaco x Topo Designs collab, part of a number of different items with the classic Topo grid pattern. These men's sandals were based on the Topo Mega Z cloud sandal. I had them a few years, but had multiple other sandals and didn't use them all that much, as soles show. Now I'm just ready to move on to a different style. I personally have always felt that Chaco whole sizes run a bit large--I'm usually 9.5 in other brands. No odor, been washed well, as pictures show.
