ClimFeet technology
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.
Thermodynamics
SoleCooler's patented principle is based on thermodynamics, and in particular on the Carnot cycle.
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.
Air compression & expansion
The cells
When you cut the cells, you can see their structure:
- Compressible cell (blue side, i.e. cold side)
- Nozzles for compression and expansion that separate the 2 types of cells
- Cell with low compressibility (red face, i.e. hot face)
Hot & cold
Here's a CFD simulation showing the temperatures obtained in a cell of our insoles thanks to compression/expansion during repeated foot placement.
With no batteries or chemicals, our insoles produce no carbon footprint during use.
