The method as the subject of the present invention relates to a method of generating heat and freshness in a flexible material, wherein the flexible material comprises a sealed unit filled with gas, and when pressure is applied to the flexible material, such as when the feet of a person or animal are pressed on the ground, or when a tire comes into contact with a road, the gas trapped in its unit is compressed and expanded.

Flexible materials are preferably made of silicone or other elastic or hyperelastic elastomers, and consist of three layers: A layer with a so-called cold battery, whose geometric shape or hardness allows for compression before the so-called hot battery, The layer with a so-called hot battery has a geometric shape or hardness that prevents it from being compressed during the compression period of a so-called cold battery, The middle layer between the first two layers, including nozzles with geometric shapes suitable for good gas expansion.

These three layers are stacked and assembled in a sealed manner, so that each so-called cold unit is connected to the so-called hot unit through one of the nozzles.

This method can be implemented in shoe soles to maintain a cool temperature when running on burning ground or keeping warm on frozen ground, as these shoe soles are therefore reversible.

At each step, the foot will compress the so-called cold chamber, and all gases will be compressed into the so-called hot chamber through the nozzle. Compressed gas will naturally heat up according to the laws of thermodynamics. When the foot leaves the ground and there is no longer compression, the flexible material will recover its volume through the elasticity of the material, and the so-called cold bubble will suck in gas from the so-called hot bubble, thereby relaxing the gas through the nozzle, which will naturally cool the gas according to the same law. As long as a person walks or runs, the cycle will continue.
