Features

Foot warmers are lightweight and compact, thus easy to take along. They work with any type of shoes and boots and are perfect for military use, hunting, ice fishing, skiing, and hiking plus for people whose feet freeze easily. Go au naturel as long as it is comfortable and then take these into use, and you can stay outside for several hours longer without freezing your toes off.

The package contains one pair of insoles, one for the left and one for the right shoe. These are in size L, which roughly fits EUR 41-44 / US 8.5-.11.

Use

The foot warmers react with oxygen, so they are activated once you open the package. They reach the temperature of 40°C (104°F) in c. 15 minutes. The insoles are self-adhesive and are attached to the outside of the sock under the foot. Thus, you don’t have to spend time trying to dig them out from the boot. Never place the insole on bare skin. They maintain the temperature for up to 8 hours and keep your feet warm the whole day.

Store the unused insoles unopened in a dry and cool place. They don’t contain any hazardous ingredients (just iron powder, activated charcoal, vermiculite, sodium chloride, and water). After the foot warmers have cooled down, you can dispose of them in the regular mixed waste.
