Despite the fact that the heat has given us a little respite in recent days, summer is still a time of high temperatures. For this reason, proper clothing is essential to keep you cool and comfortable at all times. The closed nature of the shoe makes it one of the hardest pieces of clothing to choose from… At least until the advent of these curious insoles that work like a conditioner for your feet.
Climfeet is the name of these insoles designed to refresh your feet. Installing them inside the shoes, you can feel improvement up to 4 degrees Celsius. The most impressive thing is that they do not need an external power source, and thanks to a curious design, they work like an air conditioner without electricity.
We have already seen examples of passive cooling focused on the design and materials of products, such as an air conditioner for your home that does not require electricity. Well, Bruno Aubert, founder of SoleCooler, the company behind these templates, had a similar idea in mind too. Five years later She has already put them up for sale from her official website and other services.and they cost only 79 euros.
How Climfeet insoles work, a battery-free foot conditioner
Refreshing feet was not the main idea of these insoles. According to Aubert, they were intended to help people with anemia or diabetes. These diseases tend to chill various parts of the body of those who suffer from them, with the feet being one of the most affected areas. Although there are already other insoles and socks to help these people regulate their temperature, requires an external power source such as batteries.
For this reason, the SoleCooler team set to work. Using the Carnot cycle, a principle also used in air conditioners, he created Climfeet. Thus, thanks to their knowledge of thermodynamics, they created these insoles capable of using the movement of the foot as a motorwhile the air that goes in and out of the shoe will be liquid.
Thus, instead of a heavy air conditioning compressor, these insoles use the pressure of the foot to replace it. This is how the SoleCooler manages to activate the 260 heat pumps distributed over the surface of the Climfeet on both sides.
Depending on how you wear Climfeet insoles, they can do an air conditioning or heating effect on your shoes. The cooling side is blue and the heating side is red or brown. For its part, the former consists of low compression sealed cells that work by generating heat. The latter, for its part, absorbs it, cooling the inside of the shoe. These differences in compression and connection between the two sections allow cooling or heating up to 4 degrees in just seven steps.
