Ergodyne 16992 N-Ferno 6992 Toe Warmers - Adhesive Back + Air Activated, White

The N-Ferno 6992 Adhesive Toe Warmers offer long-lasting heat, delivering up to 7 hours of warmth. Specifically designed as a heating pad for toes, they protect part of the body most susceptible to frostbite and hypothermia. As a wearable heating pad, they’re perfect for keeping toes warm for long hours during work or play. Each box includes 40 individually sealed pairs of warmers. HOW TO ACTIVATE: To activate, simply open the pack. The all-natural ingredients will begin to heat up as soon as they’re exposed to oxygen—no batteries required. Shake the pack to speed up the warming process. These toe warmers are designed to adhere to the insole of the shoe or on the sock near the toes. Once applied, the pack is safe to wear inside work boots or shoes. Packs are not reusable and should be disposed of after each use (up to 7 hours).
