Product Details
Fit
Last: 102 mm–Comfort fit designed to accommodate wider feet.
Flex
Flex: 90–A moderate flex ideal for progressing beginners and intermediate skiers.
Liner
Custom T4 Liner–Impressive "out-of-the-box" fit with unparalleled performance. T4 liners deliver a new level of optimized foot wrapping with strategically placed external features, providing a sock-like, contoured fit. External materials in key instep and heel fit-zones allow precise foot envelopment and improved interaction between the foot, liner, and shell.
Shell Materials & Design
Shell–Polyurethane
Cuff–Polyolefine
Dual Core Technology–New "power injection" method allows the simultaneous injection of two different durometers of plastic at the exact same time. This unique mono-injection process allows targeted power transmission and shell wrapping; and creates a Dual Core sandwich construction throughout the shell, resulting in livelier rebound, response, and total control through the turn.
Generative Grid Design–Focused on minimizing shell wall thickness for reduced weight while simultaneously enhancing power and support, this shell design offers the most effective blend of both for maximizing all-mountain and free-touring versatility.
Ski/Walk Mode
Hike Mode 2.0–Optimized hike mode includes a wider opening in the back of the lower shell, and a lower axis-of-rotation for optimized range-of-motion and uphill mobility (41⁰ ROM). The articulating lower shell insert and metal-on-metal locking mechanism increase rearward support while supplying maximum power transmission on descents.
