The 2026 Fischer RC4 Carbon Pro MV BOA is a high-powered boot engineered for elite-level precision and response, built around a mid-volume fit and a carbon-reinforced shell. It’s the flagship for skiers who want race-caliber power with the modern comfort and adjustability of BOA®.

Why we like it:

This boot delivers uncompromising performance without sacrificing fit thanks to Fischer’s ZipFit® liner and Boa® H+i1 system. It’s one of the most refined power-to-comfort combos on the market.

Who it's for:

Aggressive experts and technical skiers who want a stiff, snug boot that maximizes energy transmission and responsiveness.

Highlights:

A 130+ flex rating, carbon-infused TPU shell, and race-derived bootboard give the RC4 Carbon Pro its razor-sharp edge control and explosive rebound. The BOA® H+i1 Fit System dials in fit across the instep, while the RC4 ZipFit® liner enhances heel hold and insulation for more comfort and warmth. Backed by Fischer’s SOMA-TEC® stance and Race Canting platform, it’s a boot that prioritizes locked-in control and anatomical precision.

Things to consider:

This boot is unapologetically stiff and tuned for aggressive skiing—lighter or less assertive skiers will find it too demanding.

Fit & sizing considerations:

Built on a 99 mm last, the RC4 Carbon Pro MV fits snug through the midfoot , offering a dose of comfort to go with all that performance. A ZipFit® liner conforms with wear and heat; ideal for medium-width, low-volume feet seeking locked-in precision.
