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
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
PP Cuff
Liner
P4
P4 prioritizes simplicity and comfort for recreational skiers. PVC outer material, PE mid foam, and an open-cell inner deliver soft, forgiving cushioning. A supportive 10mm PE tongue adds structure without bulk. Heat-moldable and easy to fit, P4 is ideal for relaxed, confidence-building skiing.
Strap
40MM Velcro Strap
A versatile mid-width VELCRO® power strap that balances ease of adjustment with solid cuff closure. It adds extra responsiveness to boots without added bulk.
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.
Closure
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.
