solecooler's reversible insoles 'climfeet' adjust feet's temperature to keep them warm or cool

Climfeet by SoleCooler regulate feet’s temperature

Climfeet, the reversible shoe insoles by SoleCooler, automatically adjusts to the feet’s temperature and wards off heat or cold using copper and air-filled cushion cells that resemble honeycombs and bubble wraps. The reversible insoles made of silicone and copper are triggered by the pressure of the footsteps and without the use of any batteries, making them eco-friendly and free from a carbon footprint.

For Climfeet, SoleCooler relies on thermodynamics, a branch of science that deals with heat and energy transfer. Its patent uses the principles of the Carnot cycle, which is commonly used in air conditioners to cool down the air, but instead of using harmful chemicals as a coolant, Climfeet uses air as the fluid. When the user walks or runs, their feet naturally heat up the air-infused cushion cells of the insoles, and the material cools itself down as soon as it feels the change in temperature.

Reversible insoles with airtight cells

The reversible insoles Climfeet by SoleCooler have airtight cells on one side that are not easily compressible, and low-compression cells on the other side, connected by a nozzle (a small, conical hole). When the user steps on the insole, the pressure from their foot compresses the air in the airtight cells, causing it to heat up naturally. To differentiate the temperature mode, the red insoles with a honeycomb pattern heat up the feet while the blue insoles with a circular matrix cool them down.

Once the foot is lifted, the compressed air is released through the nozzle, and as it expands, it cools down naturally. This is similar to what happens when a tire is deflated, and the air coming out is cooler while the tire is warm. By using this process, SoleCooler’s reversible insoles regulate the temperature of the feet without the need for batteries or harmful coolants for all-season walking, running, or jogging.

Solecooler adds copper to climfeet to speed up heat

SoleCooler states that while it has carried out testing where about 80% of athletes in cold weather felt the insoles warming their feet after a short time, there is still a chance that some people might not feel the warmth of Climfeet right away. The company states that it might be best to use the reversible insoles for at least an hour to feel the effect and adds that their technology works best in very hot or very cold temperatures because of how it uses energy from the user’s steps.

Climfeet is hypoallergenic, except if the user is allergic to silicone or copper. The latter is added to the reversible insoles because it makes them transfer heat better, as SoleCooler claims. Climfeet looks flexible as well as spongy, thanks to its 260 air-filled cells that absorb shock well. It also seems that they can fit almost any shoe size as SoleCooler sends over a whole pad that the user can easily cut with scissors to match their shoe size. Climfeet is also washable with soap, water, or alcohol for regular cleaning.
