Technology:

TPU Coated Top and Bottom:

A rugged TPU (thermoplastic polyurethane) coating on the boot’s top and bottom adds enhanced durability, weather resistance, and structural support. This protective layer helps shield against scuffs, moisture, and impacts—keeping your boots performing and looking sharp season after season.

EliteFit Sport Liner:

This liner blends comfort and performance with a medium-volume fit and supportive ankle pockets. It’s great for intermediate to advanced skiers looking for all-day skiability without sacrificing control.

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.

Fastfit Instep:

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

BOA® Fit System:

The BOA® Fit System 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.

MultiFit™ Last:

BOA® boots with multi-fit last allow for a greater range of foot shapes to fit within the same shell family. Multi last boots are offered in three different volumes, low volume (Cortex) medium (Recon, Anthem and Mindbender) and high (BFC).

45MM Cam Buckle Strap:

A wide cam-style power strap that delivers maximum cuff support and precise closure. Ideal for high-performance boots where stiffness and control are key.

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.
