A terrible product. The info says they have &#34;breathable mesh uppers&#34; but the material inside doesn't breathe at all. Feet start to overheat and sweat immediately. Also the memory foam was so thin it compressed right away and provided little cuchioning. Also there was no arch support at all. I have slippers that are much more comfortable, breathe more, have more padding, and more support than these. They also run at least a size large and wide.
