I have not been able to enjoy the flip flops as I wanted. The flip flops are comfortable, and they fit well. The sole has good grip too. But I do not know what kind of material Crocs used to fabricate the flip flops, because they make may feet sweat like crazy. Imagine that a flip flop, where your feet are out in the open air, makes one feet sweat. I have worn military boots, and they have not made my feet sweat. I have worn all kinds off shoes and sandals, and they do not make my feet sweat. I have kept the flip flops for a long time, and still to try wear them today, and they still make my feet sweat. I washed them, and still make my feet sweat. So Crocs have used a strange material composition to make the flip flops I bought. This is the first time I have lost my money when buying at Amazon.
