Corns & Calluses are the most common foot problems and come in various forms i.e., hard corns and soft corns. These small circles of thick skin tend to form on the tops and sides of toes or on the sole of the foot. Corns are often caused by wearing poorly fitted footwear which places excessive pressure on an area of the foot. Leeford Corn Caps are self-adhesive strips easy to apply and hold firmly in place over the corn. Leeford Corn Caps contain a measured paste that loosens the skin to remove them.
