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 Pro Liner

The EliteFit Pro liner delivers a performance-driven fit with precision-mapped support zones and thermoformable foam for custom comfort. Designed for expert skiers who demand responsiveness and foot retention.

45MM Elasticated Cam Buckle Strap

This wide, elasticated cam buckle strap provides dynamic power transmission with slight give for comfort during flex. It locks the cuff securely for aggressive skiing while allowing natural ankle movement.

5355 Alpine Outsole

These outsoles have been tested with bindings representing the full range of release kinematics on currently available alpine bindings and provide release values consistent with ISO 5355-certified boots.

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, engineered & guaranteed to perform in the toughest conditions. 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.

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.

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).

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.
