The Mammut Kento High GTX is a technical alpine boot with lightweight construction. Its Hybrid Shell upper enhances performance while its Gore-Tex lining provides all-around protection. The pre-formed tongue, 2 Zone lacing, and Motion Control are auxiliary features that will grant long-lasting comfort and secure fit.

In partnership with Michelin, Mammut equipped this mountaineering boot with a Michelin Alpine Lite 3970 outsole (with poro wedge midsole). It is 40% lighter than conventional soles and is optimized for use in snowy and icy surfaces.

The Kento High GTX is a fairly true-to-size, above-the-ankle mountaineering boot that caters to men and women. It comes in regular sizes and standard width. According to the brand, it is shaped using a UK-based last that offers a wide forefoot and narrow heel fit.

To fine-tune the boot’s overall fit and volume, it uses a 2 Zone Lacing technique. This feature divides the boot into two areas so hikers can create individualized tension at the upper and lower part of the boot.

Featuring the Michelin Alpine Lite 3970 outsole, the Kento High GTX grants traction even in technical pursuits. It has a defined lug tread that works even in very low temperatures. The rigid lugs placed across the sole offers slip resistance on almost all types of terrain. It is designed with a more aggressive Climbing Zone for better performance on side approaches.

Mammut’s Kento High GTX carries a lightweight poro wedge midsole that is also compatible with crampons. The brand’s designers incorporated a footbed (also made of memo foam) to enhance cushioning and comfort.

This Mammut offering employs the brand’s Hybrid Shell feature that is a blend of inner and outer materials. It includes a premium nubuck leather used in the boot’s exterior that gives protection against outdoor obstacles. Its interior, on the other hand, uses supple materials that promote comfort. A Gore-Tex Performance Comfort laminate is added to amplify the user’s performance by making the boot weatherproof.

The pre-shaped tongue construction of the Kento High GTX yields an even distribution of pressure on top of the foot. The boot also carries the brand’s Motion Control, a feature that makes it flexible and helps prevent injury. The base of the upper is wrapped with a raised rubber rand that renders protection and amplifies durability.

The boot uses a 3D memo foam at the collar to boost comfort. Lastly, its closure system uses a series of fabric loops and metal hooks.

  • This Mammut footgear is strap-on crampon compatible.
