What it is: An injection of protein in the ball of the heel to provide a layer of extra padding and “fill out” the skin. This is a popular procedure for women who experience pain from wearing uncomfortable shoes. Oh, the things we’ll do for our love of heels. Whatever happened to just wearing flats instead?

How it works: Just like collagen fillers for your face, protein is injected to form a cushioned pad on the bottom of your foot. The effects last up to a few months, so you’ll be returning a few times a year.

Average cost: About $225 per treatment
