These things have saved my favorite shoes. Shoes I have stretched out that couldn't have been worn any longer and now I still can. So far the sticky backing is holding up with no problem. Had no problem getting them on. Color was right on. Wish they had some in red.  The straps for the nude ones I bought are much wider than some of the other pairs. Dont know if that is a fluke or an attribute of that color. Still looks fine but if you're concerned you might keep that in mind. The black ones were thinner which looked much better with those particular shoes.
