Metatarsal Shoe Cushions comfort and protect the ball-of-foot areas by relieving pressure and absorbing shock with soft, durable foam. They also add extra padding to thin-soled shoes and reduce friction to help prevent calluses. Especially effective in high-heeled shoes to ease ball-of-foot pain while stopping the foot from sliding forward in shoes. Self-adhesive backing keeps the pad securely in place. 1 Pair/Pkg.
