EDIT: It took me a couple of weeks to notice the suction cup effect on the soles of these shoes and it's TERRIBLE. Any hard surface I step on with my boots makes a "pop, pop, pop" sound as I walk. This is a terrible oversight in a great product. Please fix! I just need something that slides easily between my apartment and the in-building gym. These work great. They are SUPER easy to put on and take off as they are super flexible and they are perfectly comfortable and perfect for strength training. An absolute win for the price.
