If you have trouble wearing heels, these pads are for you.
I'm reviewing this before my son's wedding, but I will say that I rarely wear heels and I bought a strappy pair for his wedding which is this Saturday night.  I have had my shoes for 6 weeks and I ordered these pads right away, put them in, and have been practicing walking in the shoes for one hour every other night.  So far I am pleased.  They keep your foot from sliding to the toe of the shoe.  You cannot see them even in sandals.
