US 2026/0215531 A1 · THERMAL CONTROL IN SKI BOOTS

Abstract

A thermal insulation device for ski boots addresses cold feet by covering the toe box portion with a closed cell foam structure. The device may include an upper shell and side band that wrap around the top and sides of the toe box, where the device is constructed from a foam material with thermal resistance properties. The device may be thicker at the junction between upper shell and side band, may taper toward the vamp-facing edge, and the side band may terminate at a slight angle from perpendicular to accommodate boot geometry. The device can attach directly to the ski boot’s outer surface using an adhesive on its underside. Advantageously, testing demonstrates this targeted toe box coverage can maintain significantly higher temperatures compared to uncovered boots or full boot covers, without interfering with boot adjustments or bindings.

Dependent claims

A device for limiting transfer of thermal energy of a ski boot, the ski boot having a toe box portion, a toe end, a sole, and a vamp portion, the device comprising:

an upper shell structurally configured to cover a top section of the toe box portion of the ski boot;
a side band integrally connected to the upper shell and structurally configured to cover a majority of a set of side sections of the toe box portion of the ski boot;
and
an attachment structure structurally configured to connectively attach the device to the ski boot, the attachment structure including an adhesive secured to an underside of the upper shell and structurally configured to adhere the underside of the upper shell directly to an outer surface of the toe box portion of the ski boot,
wherein the device is comprised of a closed cell foam material that limits the transfer of thermal energy.
