⚡ At a Glance
- • Wearing Comfort: Ultra-thin adhesive pads sit discreetly inside many shoe types, including ski boots and dress shoes
- • Best for: Outdoor winter activities, stadium visits, Christmas markets and winter walks
- • Not ideal for: Users who need reusable or electrically powered heating solutions
Air-activated toe warmers reach an average temperature of 39°C and maintain heat for around eight hours. A natural ingredient blend reacts with oxygen while an adhesive backing allows placement on socks.
Sustained warmth – thanks to air-activated heat cells
Iron powder oxidises when exposed to oxygen, generating heat in a controlled chemical reaction that runs for about eight hours at an average of 39°C. The internal mix of activated carbon and vermiculite helps regulate heat release.
Reliable warmth for long periods outdoors, ideal for events that last several hours. Hands-free heating avoids the need for batteries or external heat sources.
Low-profile comfort – with ultra-thin adhesive pads
Adhesive pads are designed to be thin enough to fit inside varied footwear, and can be stuck to the top or bottom of socks so they stay put during movement.
Barely noticeable inside ski boots, winter boots or dress shoes, allowing normal movement without bulk. Comfortable fit reduces pressure points and slips less than loose inserts.
Ready-to-use natural heat – thanks to a simple oxygen activation and natural ingredients
Composition includes iron powder, water, salt, activated carbon and vermiculite, which together produce heat when the foil seal is removed and oxygen contact begins. No electricity, boiling or extra warming is required, and unopened packs remain stable for years.
Quick to activate within minutes and convenient to carry for spontaneous cold-weather needs. Long unopened shelf life makes it practical to keep a supply for irregular use.
