AllSett Health Insole Foot Warmers are thin, adhesive, air-activated insoles that deliver steady warmth for 10+ hours and fit inside most shoes and boots.
These disposable foot warmers come as 25 pairs (50 warmers) designed for easy activation and inconspicuous placement inside footwear. They require no batteries or cords: open the pouch, shake to start the chemical reaction, peel and stick the slim heater into your shoe or boot. Lightweight and TSA approved, they’re intended for outdoor recreation, travel, and everyday cold-weather use where portable warmth is needed.
Each insole-style warmer is engineered to provide continuous heat for more than 10 hours after activation, offering reliable warmth through a full day of outdoor activity or a long travel day. Heat intensity is steady rather than spiking, helping maintain comfort without overheating.
The warmers are slim and designed for a smooth fit inside boots and shoes so they won’t add noticeable bulk. At 8.5" × 3" with an adhesive backing, they conform to common insole shapes and stay in place during movement, maintaining shoe fit and balance.
Activation is simple: open the individual pouch, shake it briefly to expose the contents to air, then peel off the backing and press the warmer into your shoe. Allow a minute for initial heat buildup, then wear your footwear as usual to trap and distribute warmth across the foot.
AllSett Health insoles are TSA approved for carry-on luggage and are odorless and self-contained, making them convenient for trips and outdoor adventures. Because they are chemical air-activated warmers, follow package instructions and avoid direct skin contact for prolonged periods to ensure safe use.
Who is this for: These insole foot warmers are aimed at hikers, skiers, outdoor workers, travelers, and anyone who spends extended time in cold environments and needs reliable, portable heat. They’re also suitable for commuters, festival-goers, or people who want a simple, quick method to add warmth to footwear without altering fit or relying on batteries.
Q: How many warmers come in a pack?
A: The box contains 25 pairs, which equals 50 individual disposable warmers.
Q: Can I bring these in my carry-on bag?
A: Yes. These air-activated insole warmers are TSA approved for carry-on travel.
