The Sierra Women Black is a women's snowboard boot from the brand Nidecker, designed for beginner riders who want to progress comfortably.

Additionally, it features the renowned BOA® H4 Dial system, which is customizable and adjustable via a single dial on the tongue. For insulation, you will find the famous thermoformable Bronze Level liner combined with a uniquely dense insole for lasting comfort.
This ultra-affordable boot will accompany you across all terrains, ensuring optimal power transfer and well-cared-for feet.

| 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 adding weight to the gear. |
| 3D LINER SUPPORT | Excellent foot hold starting inside the liner, with a 3D moulded material and J-bars around the ankle. Minimal movement, maximum control. |
| LINER LACE | The internal lacing system is located on the liner itself. |
| 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. |
| BRONZE HEAT MOLDABLE LINER | Heat-mouldable liner ensuring toe freedom and comfort while the ankle is well supported without pressure points, thus avoiding heel lift. Comfortable and warm 8 mm PE foam. |
| 3D SINGLE DENSITY | Anatomically pre-moulded EVA foam with a silicone print on top to add traction to the sole. |
| BFT GRAVITY OUTSOLE | This sole features EVA foam for added comfort and a soft rubber toe cap for better grip. |
| 3D MOULDED TONGUE | The asymmetrical tongue is 3D moulded and curved towards the medial side, following the naturally raised crest 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. |
