The Belleville C755 Extreme Cold Weather boots are built on the proven platform of the Belleville C775 and engineered for operations in extreme cold environments. This model features a dual insulation system: 400 grams of composite Thinsulate™ insulation, plus an additional 800 grams strategically placed around the toe area for enhanced protection against frostbite. Extra foam insulation underfoot helps reduce heat loss while maintaining a lightweight feel.

A waterproof GORE-TEX membrane ensures complete moisture protection while allowing breathability. The advanced GORE-TEX THERMIUM® technology expands the comfort range across varying temperatures by adding warmth without increasing bulk, preserving agility, flexibility, and overall performance — critical for demanding professional use.

The upper is constructed from 100% cattlehide leather combined with highly durable nylon fabric. The gusseted tongue is stitched to the boot body to prevent water and debris from entering, while still allowing quick and easy on/off wear. A speed-lacing system with metal eyelets and closed hooks ensures secure and reliable fit adjustment.

Inside, the boots feature a soft lining and a removable polyurethane foam insole for enhanced comfort. The composite safety toe meets ASTM F2412-18 and F2413-18 standards.

The Vibram® 360° FIRE & ICE™ outsole is made from a specialized rubber compound that remains flexible in freezing temperatures, delivering superior traction on ice and slippery surfaces. The VANGUARD® sole construction, inspired by running footwear technology, provides excellent cushioning for long-term wear.

Berry compliant and meeting AFI 36-2903 and AR 670-1 regulations. Approved for use by U.S. Army aircraft and helicopter pilots.
