I'm a big guy. 245lbs, and these are the most comfortalble flip flop i have ever worn. In the summer months I'm in flip flops everyday when I'm not at work. So they get a lot of use. I'm on my second pair. The first pair I had repaired once. The strap between the toes pulled out first on one side then the other. I bought another pair, and I can tell there getting ready to break. I'll give them 4 stars because they are so damn comfortable.
