USED (DEMO) 2026 Fischer RC4 Free 120 MV VAC BOA — Mondo 27.5 (316mm BSL)

The 2026 Fischer RC4 Free 120 MV VAC BOA is a versatile, high-performance "crossover" boot. While the "Carbon Pro" models are dedicated to the piste, the Free series is designed for skiers who want 120-flex stiffness for resort charging but also need the utility for sidecountry or freeride exploration. This Medium Volume (MV) model features a 100mm last, providing a comfortable but secure fit for average-width feet. The standout feature is the BOA® H+i1 Fit System, which offers a superior, uniform shell wrap compared to traditional buckles. Being a "Free" model, it typically includes features like integrated tech inserts (Dynafit certified) and a more rugged GripWalk® sole for hiking. Technical Specifications Year: 2026 Brand: Fischer Model: RC4 Free 120 MV VAC BOA Mondo Size: 27.0 / 27.5 (Shared shell) Boot Sole Length (BSL): 316 mm Flex Index: 120 (Stiff / Expert Freeride) Last Width: 100 mm (Medium Volume) Shell Material: VACUUM TPU Fit System: BOA® H+i1 (Lower) + 2 Micro-adjustable Alloy Buckles (Cuff) Power Strap: 45mm Velcro Strap with Cam Buckle Sole: GripWalk® + Dynafit Tech Inserts Performance Highlights Hybrid Utility: The inclusion of tech inserts makes this boot compatible with pin bindings (like a Fischer Tour) or hybrid bindings (like the Salomon Shift), giving you the freedom to skin for your lines. 120 Flex: This flex rating is the "sweet spot" for many expert freeriders—stiff enough to drive a 105mm+ waisted ski through chop, but forgiving enough for landing jumps or navigating tight trees. VACUUM Shell: Like the rest of the RC4 VAC line, this shell can be heat-molded. If you find the 100mm last a bit snug in the forefoot, a Vacuum fit session can easily expand the plastic to provide a custom relief. SOMA-TEC®: Keeps your feet in a natural "V" stance, which improves tracking on the uphill skin track and provides better edge-to-edge power on the descent.
