Advice : Use the foot sizer from SIDAS to help you find the right size
The Altai Men Black is a men's snowboard boot from the brand Nidecker, designed for advanced riders.
If you enjoy carving or linking tight turns between the trees, you will love the Altai. Indeed, it is a fairly stiff model with plenty of lateral support, making it ultra-precise and very responsive when pushed. For ideal hold and tightening, the Altai features a DUAL BOA® lacing system that allows independent adjustment of the upper and lower parts of the boot with optimal precision for effective and comfortable tightening.
As for the Gravity + sole made of EVA foam and rubber, it offers the perfect blend of cushioning and grip when walking on icy ground. Finally, for even more comfort, the thermoformable Silver liner has been redesigned to eliminate pressure points.
In short, if you are looking for a dynamic, precise, and comfortable boot, the Altai will bring you pure joy!

| H4 COILER BOA® FIT SYSTEM | Lacing system made up of a cable and a reel that creates consistent tension and makes lacing easier for all-day comfort without weighing down the gear. |
| MID POWER DUAL ZONE BOA® CONFIGURATION | Micrometric lacing system allowing precise and independent adjustment of the upper and lower parts of your boots. |
| EXTERNAL HEEL LOCK | Our External Heel Lock works in tandem with the BOA® dial on the tongue, tightening the integrated wings on each side of the ankle to eliminate heel lift. |
| ARTICULATING FLEX ZONE | The upper cuff of the boot is asymmetrically connected to the lower boot, allowing the ankle to flex naturally while providing support without shell distortion. A thermal insulation barrier between the outsole and the bottom of the liner keeps warmth inside and cold outside. |
| SILVER HEAT MOLDABLE LINER | Completely redesigned, this liner is free of pressure points; closure is achieved via the tongue attached inside the shell, which facilitates liner entry and exit. |
| 3D MOLDED DUAL DENSITY | An additional layer of high-density EVA supports the heel and arch, while the EVA provides more flexibility in the forefoot. |
| BFT GRAVITY+ OUTSOLE | This sole features an EVA foam for added comfort and a soft rubber toe cap for better grip. |
| 3D MOLDED TONGUE | The asymmetrical tongue is 3D moulded and curved towards the medial side, following the naturally raised ridge line of your forefoot to reduce pressure points and provide a more balanced feeling of comfort and support. An anatomically correct and asymmetrical tongue performs better than a standard straight tongue. |
| 3D MOLDED TOE CAP | These toe cap designs eliminate extra layers and seams around the boot’s toe to create a durable, streamlined design with less volume and better FlowFit on your foot, and improved FlowFit in your bindings. |
