2-Piece Gel Metatarsal Cushions, Ball of Forefoot Cushions for Prevent Callus Blisters and Reduce Foot Soreness Swelling, Forefoot Pads

The gel feels good but one side fit well the other one kept curling and did not fit flat on my foot. I wore then anyway and the one the didn't stay put was less effective. The good piece was vet comfortable and actually worked to relive pain from plantar fasciitis.
