These are the best quality and performance. Water shoes I've ever owned. Had a couple other of the Asian brands but these are far superior.They are nicer than the Nike and Adidas water shoes I have spent easily three or four times as much on in the past. For the quality and the price. There's nothing close to these shoes in my experience.My use is doing gym workouts and then going to the pool to do water training and swimming and these have been perfect. The only caveat is they run a little bit large. I wear a size 12 US/46eu in most shoes. These I wear a size 11 US or size 45 European.Highly recommend you support this company for the value they have brought in the shoe.
