Features
TrueFit Last
Women's feet aren't simply scaled-down men's feet. True Form Last was developed specifically around female foot anatomy to deliver stronger heel retention, improved comfort, and a more natural fit from the moment the boot goes on.
TrueAlign Geometry
When your stance is balanced, skiing becomes easier and more efficient. True Align Geometry adjusts ramp angle, forward lean, cuff alignment, and lower leg interface to better match female biomechanics, helping skiers stay naturally centered and confident on snow.
Fastfit Instep
Mid 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 Mid Volume MultiFit Last is ideal for boot widths 97 - 100mm (Recon, Anthem and Mindbender).
Fully Heat-Moldable
Adjustable Forward Lean
Custom-fit the forward lean of the highback with the turn of a screwdriver.
Adjustable Calf
Shell
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
TPU Cuff
Liner
P1
P1 is the highest-performance P-Series liner, built for advanced to expert skiers. A Samdry™ TPU outer and dual-density construction deliver strong rebound and precise energy transfer. Laminated tongue and anatomically shaped heel and ankle create a locked-in feel with full heat-mold customization.
Strap
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.
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.
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
Forward Lean Adjustment
Collapses down tiny enough to fit in your pack for when the ice ax comes out.
