A flexible cellular material is thermoregulated by compressing and expanding gas trapped in its cells A flexible elastomer material of a device that provide thermoregulation includes two layers of different shore hardness and conductivity and is has gas-filled cells. Each cell has a zone to store the gas when compressing the material in the layer C with higher hardness and thermal conductivity and another zone to expand the gas when decompressing the material in the layer D with lower hardness and thermal conductivity. The flexible material can be used as a sole in shoes to maintain a cool temperature. With each step, the cell zones located in the layer C act as adiabatic chambers whose gasses heat with compression. When the foot leaves the ground the zones of cells located in the layer D then act as a reactor nozzle that will expand the air and therefore cool it.
