The S/Pro Supra Dual BOA® 120 blends modern fit technology with the raw power advanced skiers demand. With two independent BOA® dials—one securing the cuff, the other dialing in the lower shell—this boot creates a fully customized wrap that locks the foot in place for superior energy transfer and edge-to-edge precision. Whether you’re charging through crud, laying arcs on groomers, or exploring mixed terrain, it delivers the control you need without sacrificing comfort.

A Custom Shell™ HD process allows for quick personalization of both cuff and shell, ensuring the boot adapts to your anatomy in minutes. SensiFit™ mesh makes stepping in easy and enhances the snug, wrapped feel once the BOA® system is tightened. The Power Spine metal plate running up the back of the boot boosts forward flex and rebound, keeping response sharp and consistent across conditions.

Inside, the My Exowrap™ 4D Perf liner integrates latex-foam layering and an elastic forefoot belt to create a locked-in foothold while maintaining precise steering. The Light² footbed shaves weight while maintaining stability, and the fully customizable tongue allows fine-tuning of instep height. A 45mm Energizer strap keeps the cuff tight and delivers elastic rebound for dynamic skiing.

Durability is dialed into the design with a screw-mounted strap, buckles, oversized pivot, and toothplate—all serviceable for long-term use. Pre-mounted GripWalk pads add traction on icy parking lots and rocky approaches, so you can move confidently wherever the day takes you.
