This is my second pair. This is a good product. My main complaint is that the velcro comes loose after heavy use in the water. I use them for boating and jet skiing, the velcro is separating from the strap. The company was able to easily fix this by flashing the Velcro. It is also possible that the Velcro is rubbed when you take off your sandals. let's go boys! Great product with this simple modification.
