Yaktrax® Adhesive Toe Warmers are a safe, easy, and all-natural solution to painfully cold toes. Once opened and exposed to oxygen in the air, these disposable warmers begin working in just minutes. Apply them directly to the top of your socks to form a radiant barrier of warmth inside your shoes that lasts up to 5 hours. Yaktrax Warmers are the ideal choice for outdoorsmen, winter athletes, spectators, and anyone who works or plays outdoors.

HOW IT WORKS

When exposed to oxygen in the air, the iron filings inside the pouch begin to oxidize creating a rapid rusting process which in turn produces residual heat. Salt acts as a catalyst, while carbon helps to evenly disperse the heat. Vermiculite acts as an insulator that helps prevent the heat from dissipating too quickly.
