ClimFeet is the first reversible insole capable of creating heat on one side and cold on the other without batteries. The sole uses the thermodynamic process of air compression and expansion to create heat on one side and cold on the other.<\/p>

The effectiveness of this technology has been confirmed by an independent scientific study conducted in the LEPSA (University of Perpignan)<\/strong> and published in Computer Methods in Biomechanics and Biomedical Engineering<\/em>.\u00a0Download the study (PDF)<\/a> – See the official reference (DOI)<\/a><\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Thermodynamics<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

SoleCooler's patented principle is based on thermodynamics, and in particular on the Carnot cycle.<\/p>

To reproduce this thermodynamic cycle in an insole, we devised and patented a new process that uses foot pressure on the ground instead of a compressor: low-compression cells on one side and high-compression cells on the other, linked by nozzles (small conical holes) to optimize compression and separate flows.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
