The Promachine 85 W is proof that a flexible ski boot can be well-fitted and provide high performance. Designed for lightweight skiers who exert subtle pressure on their ski boots, the Promachine 85 W features a low-volume, lightweight shell of 98mm. This makes it dynamic and responsive, performing equally well on groomed slopes, bumps, or in chopped-up snow. The Primaloft® insulation of the liner enhances comfort and warmth, while the articulated rear collar specially adapted for women provides more space for the calf. Even though the flex of the Promachine 85 W is soft, the edge of the shell is made of a stiffer plastic to ensure good lateral stability and rapid energy transfer, making it extremely responsive and precise. The Promachine 85 W is perfect for skiers who want a flexible ski boot without compromising on fit.
