RC4 95 MV BOA Ski Boots 2027

The Fischer RC4 95 MV VAC BOA is a high-performance all-mountain ski boot built for skiers who want the full RC4 technology package in a more accessible, comfort-oriented flex. With a 95 flex and a 100mm medium-volume last, this boot delivers genuine precision and responsiveness for on-piste carving and all-mountain skiing while remaining forgiving enough for longer sessions and varied terrain. It punches notably above its flex rating — testers consistently report it skis stiffer and more powerful than the number suggests.

The VACUUM shell technology uses Fischer-exclusive Vacuplast plastic, which can be heat-moulded by a bootfitter to precisely match the contours of the foot — the only technology that simultaneously reduces and expands shell volume for a truly custom shape. The BOA H+i1 Fit System provides micro-adjustable shell wrapping for a secure, precise fit across a wide range of foot shapes. An iFZ Performance liner — developed with Fischer's Scan-Fit data for an optimal fit — delivers thermoformable comfort and warmth, while the Grindable Bootboard and RD20 Race Canting allow professional bootfitters to dial in stance precisely. 

Features

• BOA H+i1 Fit System — high-power micro-adjustable closure that wraps the shell precisely to the foot for a locked-in, confident fit
