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.

A method of assembling a boot is provided. The method comprises forming a first layer of insulation material of the boot covering a toe region, a saddle region, and a heel region of the boot; forming a second layer of insulation material of the boot that covers the saddle region and the toe region and does not cover the heel region of the boot; forming a third layer of insulation material that covers the toe region and does not cover the heel region and the saddle region of the boot; and attaching the first, the second, and the third layers of insulation material to an outsole of the boot.

A textile including a radiant barrier, the textile comprising a proximal side and a distal side. The textile also comprising a first substrate and a second substrate. The first substrate disposed distally of the second substrate. An insulation layer disposed adjacent to the second substrate; and wherein at least one of the first substrate and the second substrate is a radiant barrier, and wherein the radiant barrier has an average thickness of between 20 nm to 150 nm.

A cover for athletic shoes, namely running shoes which provide protection from the elements such as rain, sleet, snow and cold temperatures. The cover should be non-obtrusive, not substantially detract from the aesthetics of the underlying shoe chosen by the wearer, while also being durable and inexpensive to manufacture. The cover should also not reduce the overall performance of the sole. The covers are lightweight, tuck easily into a small pocket, and quickly removable for ease of use.
