NEW 2026 Fischer RC4 Carbon Pro LV BOA - Mondo 27.5 (316mm BSL)

The 2026 Fischer RC4 Carbon Pro LV BOA in the striking Yellow/Carbon colorway is an elite-level racing and high-performance piste boot. This Low Volume (LV) model is specifically engineered for skiers with narrow feet who demand a "zero-slop" connection to their skis.The defining feature of this 2026 model is the integration of the BOA® H+i1 Fit System, which provides a superior shell wrap and more consistent pressure distribution across the forefoot than traditional buckles. This is paired with a CARBONFUSED® Cuff, ensuring the boot provides massive lateral stiffness and an explosive, high-energy rebound. Inside, the inclusion of a stock RC4 ZipFit® Innerboot—the professional standard for performance liners—uses a cork composite to deliver an uncompromising heel hold that won't pack out over time.

CARBONFUSED® Stability: The carbon-infused TPU shell and cuff maintain their stiff flex even in warm spring conditions, ensuring consistent performance from the first chair to the last. ZipFit® Advantage: The cork-filled liner is heat-moldable and "re-moldable," meaning a bootfitter can add or remove cork to perfectly contour the liner to your ankle and shin for total power transmission. GripWalk® Convenience: While it offers race-room performance, the GripWalk soles provide essential traction for walking on icy surfaces or across the parking lot.
