Grabber Foot Warmers are single-use air-activated heat packs that provide 5+ hours of continuous warmth for your feet. Simply open the package, slide into the bottom of your boots or close-toed shoes and let the heat sooth your cold or aching feet. Grabber Foot Warmers are specifically designed for use inside a shoe or boot where oxygen is restricted. Do not trim or peel. Place the fabric side up and white side down.
The Grabber Warmers contain natural ingredients that when exposed to air react together to produce heat. This is accomplished through a rapid oxidation process. Ingredients include iron powder, water, salt, activated charcoal, and vermiculite. Grabber Warmers has perfected the process so that our warmers, depending on the individual product, produce heat anywhere from 100°F to 180°F for a duration of 1 to 20+ hours.
