Helpful in the right shoes when applied properly
I initially tried putting these in an older pair of athletic shoes in which the rear heel padding area had been torn up a bit and I needed some additional padding.  I had a couple of problems with it.  First, because of the torn material, the pad did not stick well or hold in place.  I don't feel that these are great for shoes that have a material for the back of the heel area since it can't really stick well to that material.  The second problem I had was that when I first put it in, I put didn't get it in perfectly straight and at the proper level.  The problem is that you really only get one shot at that since you really can't move it after it sticks (or it will lose its "stickiness").  So my second lesson I learned was to to make sure you get it right where you want it on the first attempt.<br /><br />I then tried them on some boots that are slightly oversized and in which my heel slides up when I walk.  They work very will in this case.  There was a clean and firm area in the back of the boot to which to attach.  I kind of test fitted them prior to removing the backing and then after removing the backing, I folded them in half, got them in position, and then applied them carefully and pushed them on firmly.  So far they are working well.  I am a little concerned whether I will push them off when I insert my foot into the boot over time.  I will have to wait and see on that.<br /><br />SUMMARY:<br />They work well on the right type of shoe or boot, but make sure you get them right where you want them on the first attempt since any attempt to adjust their position will reduce their ability to stick well.
