I think this is what I've been looking for!
I have previously bought thick moleskin and "created" new heel cushioning in my workshoes.  They wear out so quickly and not really all that cushioned.  I wear a mens size 10 1/2 and these are the perfect size.  They are soft and cushiony and they seem like they are going to stay put and best of all I only have to peel off the backing and stick them to the heels of my shoes. I am ordering another pair right away!
