BEHIND THE PRODUCT
BEHIND THE PRODUCT
The Altai is the centerpiece of Nideckers' 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.

In-depth Tech Specs:
- BOA® - The industry standard in speed lacing systems. Micro-adjustable for a precise fit and engineered to perform in the toughest conditions.
- Dual-Dial BOA® Closure System - Dual-Dial BOA® lets you tighten your boots quickly and easily via two dials. The upper and lower foot can be adjusted independently for a custom fit, and to prioritize maximum power transfer or looser, more surfy turns.
- Silver level Liner- Heat molding allows you to customize the fit of our versatile Silver liner, which also features a Custom Flex Zone around the toes for extra wriggle room, 8mm of PE foam and additional PU support. The liner is closed via a separate cuff connected to the inside of the shell, making it a breeze to get on and off. Velcro patches on both sides of the tongue help secure the fit.
- 3D Dual Density Insole - 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.
- Gravity+ Outsole – 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.
