The indented channel on the inside guides the heel and keeps the foot in position. This extra wide sock aid is ideal for people with larger feet or edema. To use this sock aid, slip the sock over the end that does not have the strap. The black textured circle on the back of the sock aid holds the sock in place. While sitting down, lower the sock aid to the floor in front of your foot using the strap. The Rigid Sock Aid holds it shape and keeps the sock open.
