Don't stay on
Tried these on several different pairs of shoes and they never stayed on longer than a couple hours.  Two of the pairs I put them on were brand new and the third pair I tried them on had been worn, but I cleaned and dried the bottom of the shoe before putting them on.  No luck, every time they came off.  Tried them on a pair of pumps as well as a pair of ballet shoes.
