TPU Shell

TPU is the benchmark material for alpine ski boots, delivering a smooth, progressive flex with outstanding durability and dependable performance across a broad range of temperatures. Its balanced feel provides predictable power transfer, strong edge control, and all-day confidence, making it an ideal choice for skiers who value precision without sacrificing comfort.

Cuff

PP Cuff

Lightweight and durable, our polypropylene cuff delivers consistent flex and reliable support in all conditions. Engineered for comfort and performance, it’s an ideal choice for skiers seeking value without compromising on control.

Liner

Cushfit Comfort

Same great fit and out-of-the-box feel as our classic Cushfit liner, but with additional foam in key areas for increased comfort and compliance

Outsole

GripWalk Outsoles

Removable and interchangeable ISO 23223 alpine rockered soles collaboratively designed to work with Marker’s Grip Walk binding system for better grip and added comfort when walking and standing in boots, but doesn’t compromise the power transmission and release function between the boot and binding when skiing. Preinstalled.

Slim and simple, the 30mm VELCRO® strap is lightweight and user-friendly, offering a secure closure for recreational skiing. Perfect for boots where comfort and convenience are top priorities.

Features

Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.

High Volume MultiFit Last

The MultiFit Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes and ensure a better, more secure fit. The High Volume MultiFit Last is ideal for boot widths 96 - 98mm (BFC).

Fully Heat-Moldable

Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.

Powerfuse Spyne

A rear co-injected “Y” shaped support that adds strength and power to the Energy Interlock in order to maximize fore/aft flex efficiency and lateral stiffness for responsiveness in every type of terrain.

Hands Free Entry

Dual material overlap for intuitive and easy hands-free exit and entry.
