Say goodbye to cold feet with Häago Foot Warmer Insoles! They are the ideal winter companion and can be used in all sorts of conditions, from snowy mountain tops to wintery days closer to home. Just place them in your shoes and have warm feet for the rest of the day!

Each insole contains natural ingredients only - iron powder, activated charcoal, vermiculite, water and salt - which means they can be fully recycled. As soon as the outer packaging is opened, a natural exothermic reaction takes place between the iron powder and the oxygen in the air. Salt helps to speed up the process, while the activated charcoal disperses the heat created from the reaction.

In just 5 minutes, the warmers can reach a temperature of 58 degrees Celcius. The vermiculite acts as an insulator and helps to maintain the temperature for up to 10 hours. This is perfect for skiing, snowboarding, winter hikes, running, outdoor activities and general winter use, and promises to keep cold feet at bay!
