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.

Strap

45MM Power Band

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.

Features

Fastfit Instep

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

Integrated Toe Tech Fittings

Tech fittings in the toe are fully integrated into the shell injection, allowing for compatibility with certain tech bindings and alpine DIN bindings.

Low 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 Low Volume MultiFit Last is ideal for boot widths 96 - 98mm (Cortex).

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.

BOA® Fit System on the Cuff and Shell

The BOA® Fit System shell delivers dialed in performance and a micro-adjustable precision fit. It consists of three integral parts: a micro-adjustable dial, lightweight yet extremely strong laces and low-friction lace guides, which are applied in uniquely designed configurations to improve the fit and performance of the boot.

The BOA® cuff single cable design allows the tension to self equalize always giving a consistent pressure to the shin. The improved wrap allows for better power transmission and improved comfort even at high tension
