Non Woven Grey Heel Grips are adhesive pads typically used inside shoes to prevent heels from slipping or rubbing against the back of the shoe. They are made from non-woven fabric material, which is a type of textile that is produced by bonding or felting fibers together. These grips are commonly chosen for their discreet appearance, which blends well with the interior of most shoes. The primary purpose of Non Woven Grey Heel Grips is to prevent the heel of the foot from slipping or rubbing against the back of the shoe, which can cause discomfort, blisters, and friction-related injuries.
