I do aqua aerobics at a local Y three times a week. The pool bottom was hard on my feet so I decided to give it a try and they work great. They stay in place, don't interfere with my workout at all, and don't break my toes anymore.
Pros
Everything is fine with this purchase. Like the looks. It's easy to get in.
Cons
Order a size or two up as they run small. I have shoe size 10, I ordered size 10/11 and they were too small.
