Great answer to problem!
I am so pleased with these heel liners.  I seem to have a lot of trouble buying shoes that I like, only to find that my heel slips out of the shoe when I walk.  And it's not that the shoes are too big, it's just either the heels are too wide or my heel is narrow.  I tried buying the gel heel liners at the store, but because they have a slick surface, it really did nothing to help my issue.  These heel liners have soft "nubs" rather than a slick surface against the skin and are magic to me.  They adhere strongly to the inside of my shoe.  Have not had any problem with it peeling up.  Only word of caution is that the added thickness may make your shoe tighter overall, so just be aware.
