Alpine Ski Boots
The undisputed benchmark in the high-end performance All-Mountain category, the third generation of the Speedmachine series by Nordica combines the direct power transmission of a racing boot with the ergonomics and cushioning needed to ski any terrain all day long.
3 Force Construction and Honeycomb-Reinforced Transmission
3 Force technology is based on an anatomical three-material design: a rigid outer structure that wraps around the heel and sole, directly connected to the plastic spine to instantly channel every skier impulse to the ski edges. This architecture incorporates a lightweight chassis with a honeycomb matrix (Honeycomb) that reduces the boot’s overall weight while maximizing lateral torsional stiffness at high speed. It is complemented by elastic instep flaps (Easy Entry Soft Flap), allowing smooth, effortless entry and exit even in very low temperatures.
Medium MV Last (100 mm) and Sporty 120 Flex
With a balanced 100 mm last in reference size 26.5, it provides the snug, precise fit demanded by technical skiers, while ensuring sufficient room for optimal blood circulation and lasting warmth. Its responsive 120 flex delivers solid, elastic forward support through the end of the turn, ideal for driving demanding carving skis or wide freeride skis with complete control on hardpack, variable snow, or moguls.
3D Custom Cork Fit Liner with Primaloft® Insulation
The 3D Custom Cork Fit inner liner features a moldable natural cork insert at the heel and ankle bones, providing an immovable anatomical hold, instant mechanical response, and remarkable vibration-dampening capability. The inner lining with Primaloft® thermal fiber keeps feet dry and warm in adverse weather conditions. In addition, the shell features Infrared technology, allowing bootfitting specialists to customize specific pressure points through selective heating in just a few minutes without compromising the polyurethane plastic’s structural integrity.
Official GripWalk Soles and Micro-Adjustable Buckles
They come standard with curved-profile soles featuring GripWalk (GW) rubber compound, substantially improving grip and walking ergonomics in parking lots, on stairs, or on icy surfaces. Their 4 low-profile aluminum micro-adjustable buckles and wide 45 mm Powerstrap ensure an even, progressive fit without excessive pressure points on the shin.
