BOA® Fit System
The BOA® Fit System delivers precise, micro-adjustable performance. It combines an adjustable dial, lightweight and extremely strong cables, and low-friction guides to distribute pressure evenly around the foot for a secure and comfortable fit.
CushFit Comfort
The CushFit Comfort liner provides a comfortable feel right out of the box, with additional foam strategically placed in key areas for increased comfort and compliance.
TPU Shell
TPU is a benchmark material for alpine ski boots, providing a smooth, progressive flex, outstanding durability, and dependable performance across a broad range of temperatures. It delivers predictable power transfer and strong edge control.
GripWalk
The preinstalled GripWalk ISO 23223 outsoles feature a rockered profile designed to provide better grip and increased comfort while walking and standing in ski boots.
FastFit Instep
Softer TPU material is used around the instep to make getting into and out of the boot quicker and easier.
High Volume MultiFit Last
Developed in conjunction with the BOA® Fit System, the MultiFit Last accommodates a variety of foot shapes to provide a more precise and secure fit.
Adjustable Calf
A 50 mm adjustable cuff provides a more personalized fit around the calf.
Après Mode 2.0
The Après Mode 2.0 walk mode provides up to 50° of range of motion. A lever at the back of the boot releases the upper cuff from the lower shell for increased comfort and convenience while walking.
Fully Heat-Moldable
Both the shell and cuff can be heat-molded to accommodate different foot shapes and provide a more personalized fit.
Powerfuse Spyne
A rear co-injected Y-shaped support increases lateral stiffness while improving fore/aft flex efficiency for greater responsiveness and power across a variety of terrain.
Hands Free Entry
The dual-material overlap construction makes getting into and out of the boot easier and more intuitive.
