I seached for and reseached these flip-flops for a long time. I like flip-flops in the summer but I can't stand flat footed cheap ones. These are molded to fit your foot and are suited for all terrains and fit well. Some people claim that it takes some getting used to the covered big toe thing and that the toe post is thicker than most flip flops. I didn't have any of these issues. I have other Keen sandals that run a 1/2 size small so I ordered a half-size bigger on these. I think these are more true to size as I probably would have been okay with my actual size. The only negative thing I can say about them is I wish they came in more colors and/or leather. But they don't make them like that any more.
