RC4 120 MV BOA Boot - 2026

What Our Gearhead® Experts Are Saying:

"I skied the RC4 120 MV BOA during a full weekend at Mammoth and was blown away. The BOA system gave me the most even wrap I’ve ever felt in a boot—no hotspots, no pressure points. Paired with the iFZ liner and VACUUM shell, it felt custom right out of the box. It’s powerful, precise, and surprisingly comfortable for a 120 flex."

When we step into the RC4 120 MV BOA Boot, we're locking into more than just a ski boot—we’re locking into control, precision, and performance born from relentless innovation. Built by Fischer, this boot meets the needs of demanding all-mountain and piste skiers who expect power with comfort and a fit that doesn’t quit.

With a medium-volume 98mm last, the RC4 120 MV BOA adapts to a wide range of foot shapes thanks to the micro-adjustable BOA® Fit System. The iFZ Performance liner molds effortlessly to your anatomy while the VACUUM shell enhances fit and performance with heat-moldable customization. When conditions change, GripWalk® soles keep us secure whether we’re traversing icy parking lots or hiking for sidecountry turns. This is how confidence feels—dialed in, locked in, and ready for every run.
