I bought these in February 2017 and have been using them at the gym at least 4 days a week for the past 9 months. I use them in the sauna, steam room and shower. I don't know about the quality of the product as I only ordered one pair. However, considering how often I use them and what I use them for, I find them to be durable, comfortable, and way better than some other types and brands of shower shoes. Sole, with an "insert" of a different color on which the insole rests. Contrary to a review someone previously posted, I don't see any signs of a breakup. The shoes have no odor other than a slight odor associated with the construction materials. As far as I can tell, these shoes are waterproof. They don't record anything. When I finish my workouts, I usually either towel dry them off or shake off the excess water and throw them in the wet pocket of my bag. I recommend, like any wet thing that needs to be dry, taking it out to dry as soon as you get home. This shoe will only stay clean and dirt-free if you leave it that way. If you leave them wet in your bag, toss them with a pile of wet gym clothes and store them that way, then something is likely to be brewing somewhere. But that's the owner's fault, not the shoe's. I will buy it again for my next pair if it ever wears out, which doesn't seem to be the case. As already mentioned, we hope for a consistent quality in their manufacture and testing.
