What Our Gearhead® Experts Are Saying:"I’ve skied the Promachine 105 on everything from icy frontside laps to soft bumps and it holds up every time. The low-volume 98mm fit hugs the foot without being punishing, and the customizable cork liner adds warmth and precision. It's a performance boot I trust when conditions and terrain vary."We demand more from our boots—and the Promachine 105 Ski Boot delivers. Built with a narrow 98mm last and a responsive yet forgiving 105 flex, this boot brings together high-performance control and all-day comfort. From early groomer laps to steep off-piste runs, we love how this boot seamlessly transitions with us across terrain and snow types. Nordica crafted the Promachine 105 with a tri-force shell that efficiently transfers energy for maximum edge power, while the 3D Cork Fit liner with Primaloft® insulation keeps our feet secure and warm. With Infrared heat customization for dialing in the perfect shape, a women’s-specific cuff for better calf fit, and GripWalk soles for better traction in the lot or on boot packs, this boot doesn't just perform—it adapts to our adventure.
