Worked for me! Good product!
This grip, so far, lasted through a dinner auction and wedding (with a lot of dancing), is not peeling away from my shoes, and is preventing my heels from slipping out of the shoe.  Another nice thing is the pack came with three pairs of heel grips.  Have not needed to use a second pair though.  Tried the heel grip from this seller after having tried a similar product that I found at a local shoe store, which started peeling off my shoes during the first outing.
