The heated insoles we’ve seen generally use batteries to generate electrical heat to warm frozen toes. French company Solecooler has a different idea. Bypasses electrical hardware and draws power directly from the foot itself. Its insole uses mechanical energy from the basic stepping motion to drive integrated heating and cooling elements. The reversible, double-sided design allows the wearer to simply flip the sole to achieve the opposite effect when the seasons change.
Whether the wearer places the Climfeet insole cool side up or heat side up, either side works via basic physics to produce the desired effect. When the wearer dismounts, the soft, foam-like pods on the cooling side compress the air into compact, reinforced cells on the warm side, with air compression delivering a heating effect of up to 4 ºC (7.2 °F). produce. As the stride moves upward, the air expands back into the soft cells on the cooling side, creating a cooling effect of up to -3.5 ºC (-6.3 °F). You can wear it according to the weather under your feet because you can only feel the effect corresponding to the upward direction.
Climfeet insoles use a combination of silicone and copper in their construction to ensure flexibility and efficient thermoregulation. Air cells also create natural cushioning to absorb impact and enhance overall comfort.
Solecooler acknowledges that Climfeet’s effects aren’t as dramatic as battery-powered climate control systems, but says it’s more uniform and avoids the hot spots associated with electrical design. Unlike batteries, it maintains energy as long as the wearer continues to move.

Solecooler also points out that Climfeet’s regulating effect is most pronounced, especially in hot or cold weather, and may not be noticeable in moderate temperatures between 20-30 ºC (68-86 ºF). I have to admit I’m skeptical about how much difference users will notice in very hot or cold conditions, but unless you’re wearing a pair in the cold of winter or the heat of summer, you can be sure.

Solecooler designed the Climfeet with a variety of end users in mind, including workers working in extreme cold and hot environments, outdoor athletes, military and first responders, and even pets walking in hot and cold weather. . We also identify a potential user group that does not benefit from alpine skiers. Given the tightness of ski boots and the lack of walking when riding lifts or sliding downhill, skiers cannot generate adequate motion to enable the heating effect. This points to a more general drawback. Because the Climfeet relies on motion, it cannot provide effective warmth when the wearer is still, when their feet tend to be the coldest.

Solecooler won a spot in the first round of the 2023 ISPO Awards this month. This was probably helped by the fact that the judges judging from the chilly range of an igloo village near Innsbruck, Austria.Climfeet insoles are currently available for a retail price of €65.83 (US$71). Solecooler ships worldwide, but shipping is billed separately.
