Saved my sandals
I have several pairs of sandals with rubber bottoms that I was going to have to dump (like a previous pair) if I didn't protect the heal. Shoe repair places wanted more than what the shoe cost and they only had black heal guards.  So I purchased these and found a local store that would fix them for $10. I don't think this is a product you can do it yourself and have a satisfactory result compared to going to a professional.
