HeatPaxx Insole Warmer

Air-activated insole warmers for sustained foot warmth in cold-weather operations and outdoor use.

The HeatPaxx Insole Warmer is a disposable, air-activated heat pad designed to be worn directly inside a shoe or boot. Once removed from packaging and exposed to air, it begins generating heat within minutes and maintains warmth for 5 hours or more. The ultra-thin, flexible, non-slip construction means it sits unobtrusively underfoot without affecting fit or comfort.
