I bought this idem hoping it would aid me in being able to move more smoothly to the zumba moves, while they worked, they kept coming off of my exercise shoes and made it harder to keep them on because they came off during the workout and the grip on the bottom of the shoe caught making it impossible to go one without stopping to put it back on. I would not suggest buying these, you may be happier like me by simply buying a smoother bottom shoe that won't catch, then to fight with these.
