Nidecker Altai Snowboard Boots

Double BOA®, medium stiffness, versatile.

Conquer any terrain

The "Altai" is the cornerstone of our boot collection, offering top-quality performance and control at an unbeatable price. It is built around an asymmetric upper that eliminates pressure points, with Dual-Dial BOA® dials that let you tighten the upper and lower zones independently. The responsive, medium-stiff flex is perfect for carving groomers or precisely slicing through powder in the trees. If you love turning technique, you will love this boot.

Key features

• The lightweight "Altai" "Gravity+" outsole delivers excellent cushioning and grip, while the rubber toe edge boosts traction on ice and rocks.
• Our "Transition Zone" technology smoothly blends the "Altai" outsole into the "Exo Spine", speeding up response and protecting the heel of the boot from damage when stepping in or out of bindings.
• The heat-moldable "Altai" Silver Liner can be customized if needed, yet is comfortable straight out of the box.

Dual-dial BOA® / external heel lock

The lower part of the boot is tightened with a side dial, while the tongue dial controls the upper zone and our unique external heel lock.

BOA® Fit System

H4 reel

Outsole - Gravity+

Our "Gravity+" outsole, made from a single piece of waterproof, lightweight EVA, cushions the feet superbly. The tread pattern is inspired by snowboard tracks, and the rubber section at the toe ensures reliable grip in icy conditions.

Liner - Silver level

Heat molding lets you customize our versatile Silver-level liner, which also features a Custom Flex Zone around the toes for extra room to move, 8 mm PE foam and additional PU support. The liner fastens with a separate strap connected to the inner shell, making it easy to put on and take off. Velcro straps on both sides of the tongue improve the fit.

Liner closure - Frame laces

Pull the inner laces to tighten the straps attached to the frame. Velcro secures the tongue.

Insole - 3D triple density

Our most advanced 3D insole is designed to fit your foot perfectly. It is made from three densities of EVA: a firmer material supports the heel cup and arch, while a special high-grip layer sits at the heel. The wool-lined footbed with a silicone top print provides warmth and security.

Boot features

• BOA® - The industry standard in quick-lace systems. Micro-adjustable for a precise fit and built to perform in the toughest conditions.
• 3D profiled tongue - Our asymmetric 3D Molded Tongue is more curved toward the medial side to match the natural ridge line of the forefoot. This reduces pressure points and delivers a more balanced feel of comfort and support than a standard straight tongue.
• 3D molded toe box - Our 3D toe box removes extra layers and seams around the forefoot, increasing water resistance and durability. The simplified construction also makes it easier to step in and out of bindings.
• ASYM 3F - A unique asymmetric boot construction developed together with BOA® that creates optimal support and flexibility. The asymmetric tongue has lace guides positioned on the flatter areas of the forefoot for more even closure and less point pressure. Increased medial arch support reduces foot fatigue and cramping.
• Rubber backstay - A durable heel section that protects the boots from wear. Our unique transition zone means the rubber blends smoothly into the outsole with no edges, so no cracks form when securing the bindings.
