I just got them this week and have only used them a couple of times. They seem to be excellent quality. Obviously, I can't speak to how well they will hold up over time.I can say, they are comfortable and they feel secure, they fit well and that includes the strap that goes under your shoes. Even with my big feet.I also found out the first time I used them, that there is a right and left, and that does make it easier to put them on your feet.I would definitely buy these again.See full review
