The Altai is the centerpiece of Nidecker's boot collection, offering premium features and support at an exceptional price. It’s built around an asymmetrical upper that minimizes pressure points, with dual H5 BOA® dials to allow you to tighten the upper and lower sections independently. The responsive, mid-stiff flex is great for digging trenches in the piste or floating through forests with pinpoint accuracy. If you love the art of the turn, you’ll love this boot.

Wide Fit
Closure: Dual BOA® - Dual BOA® technology provides quick, precise lace adjustments via two independent dials. Each controls a distinct boot zone, delivering a custom fit in seconds
BOA® Fit System: H5 Coiler - The next evolution in BOA® technology features micro-adjustability – simply turn the dial in reverse to gradually release tension and fine-tune your fit. Lower profile design gives the boot a clean look and reduces snag risk
External Heel Lock: Nidecker's External Heel Lock works in tandem with the BOA® dial on the tongue, tightening built-in wings on either side of the ankle to minimize heel lift
Outsole: Ascent 2.0 - The Ascent 2.0 builds on the original version with an improved Transition Zone™ and stiffer, more durable heel rubber for enhanced compatibility with speed entry bindings. Upgraded rubber traction at the forefoot and heel delivers superior grip
Liner: Silver - The Silver liner can be heat molded for a custom fit and features a Custom Flex Zone at the toes, 8mm PE foam, and added PU support. A separate cuff connected to the shell ensures easy entry, while touch fasteners on the tongue secure the fit
Liner Closure: Shell Harness - Pull the inner laces to tighten a shell-mounted harness. Touch fastener secures the tongue
Insole: 3D Pro A performance footbed combining EVA and TPE foam in a single 3D-molded piece for next-level comfort with long-lasting rebound. Features a breathable mesh top layer for increased warmth and grip
Asym 3F: A unique asymmetrical design co-developed with BOA® for balanced support and flex. The tongue's lace guides are positioned over flatter forefoot areas for even closure and reduced pressure points. Enhanced medial arch support fights foot fatigue
Articulating Flex Zone: The upper boot cuff is asymmetrically connected to the lower boot, allowing the ankle to flex naturally and providing great support without shell distortion
3D Molded Toebox: Nidecker's 3D Toebox minimizes extra layers and seams around the forefoot, improving water resistance and durability. The streamlined design also makes it easier to slide your boot in and out of the binding
3D Molded Tongue: Asymmetric 3D Molded Tongue features a sharper curve on the medial side to match your natural forefoot shape. This design minimizes pressure points and delivers more balanced comfort and support than a traditional straight tongue
Flex: Mid-Stiff (3/5)
Terrain: (Resort): 4/5 (Pow): 3/5 (Park): 3/5
