Say no to blisters and rubbing! Heavenly Heelz are designed to give you relief from uncomfortable shoes that dig at your heels. Each back-of-heel cushion is made from PORON®, a lightweight, breathable foam material that keeps feet cool and dry. Worn with or without socks, Heavenly Heelz prevent slipping and sliding inside your shoes. Plus, a Spectape™ adhesive backing keeps the inserts locked into place for repeated wears.
