2026 NIDECKER Altai BOOT

The Altai is the centerpiece of our boot collection, offering premium features and support at an unbeatable price. It’s built around an asymmetrical upper that eliminates pressure points, with Dual-Dial BOA® laces 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.

Key Features

• The Altai's lightweight Gravity+ outsole delivers awesome cushioning and traction, with a rubber toe-tip to boost grip when hiking over ice and rock.
• Our Transition Zone tech seamlessly connects the Altai's sole to the Exo Spine, accelerating response and preventing damage to the back of the boot when entering or exiting the binding.
• The Altai's heat-moldable Silver Liner allows you to customize the fit if you need to but is comfortable straight out the box.

CLOSURE SYSTEM

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

H4 Coiler

Ready for anything, designed to withstand. The bombproof BOA® H4 Coiler is built for the most demanding riders and resists impacts from park to pow. Its efficient mechanism rapidly takes up lace slack, increasing speed of entry.

HEEL LOCK

External Heel Lock

Our External Heel Lock works in tandem with the BOA® dial on the tongue, tightening built-in wings on either side of the ankle to eliminate heel lift.

OUTSOLE

Gravity +

Constructed from a single piece of bombproof and lightweight EVA, our Gravity+ outsole delivers great cushioning underfoot. The tread pattern is inspired by snowcat tracks, with a rubber section at the toe for reliable grip in icy conditions.

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 Velcro patches on the tongue secure the fit.

LINER CLOSURE

Shell Harness

Pull the inner laces to tighten a shell-mounted harness. Velcro secures the tongue.

INSOLE

3D Dual Density

Anatomically designed to cradle your foot and constructed from two densities of EVA, with firmer material supporting the heel cup and arch. A fleece-lined footbed with silicone top-print keeps you warm and secure.
