Sort of work....
They sort of work, depending on what you're needing them for. They do not keep my heel from slipping out of the back of my shoes but they have prevented irritation on the backs of my ankles. They adhere SUPER GOOD to the shoe and do NOT come off when you're slipping your shoes on and off - even if it's a tight snug fitting shoe. The odd thing, that I did not expect, is that you have to put them kind of far down in the heel to prevent them from being seen out of the top of the shoe - which I suppose only presents a visual problem if you're wearing ankle pants.
