Ingenious warming insole without batteries or wires.
Turns kinetic energy into heat with each step. Swiss quality product.
The result of years of material research and development.
The heat-generating effect is based on a specially developed polyurethane foam which is compressed and relaxed again with every step. The resulting friction generates warmth and the surface temperature rises up to 10°C (5mm sole) or 5°C (3mm sole) after only approx. 12 minutes of walking.
In 2 thicknesses: For virtually every shoe, during autumn, spring and winter.
In winter, wear the 5mm thick chili-feet insole in boots, hiking and work shoes, and while cross-country skiing or hiking. The thinner 3mm sole is ideal for the transitional seasons, and fits perfectly in running shoes, business shoes and court shoes.
Comfortable, shock-absorbing and hard-wearing.
Warming effect for at least 1.5 million steps. Suitable for anyone weighing more than 48 kilos (106 lbs). Can be cut to size 35 to 47. Washable up to 30°C.
Prominent athletes also swear by chili-feet soles.
Adventurer and mountaineer Evelyne Binsack benefited from the warming effect of the chili-feet insoles when climbing Mount Everest and on her expedition to the North Pole.
Biathlete Susi Meinen, member of the Swiss National Squad, is also convinced: “The chili-feet insoles are my number one choice against cold feet”.
