FISCHER RC4 120 MV VAG GW Men's Ski Boots (U06323V)

The Fischer RC4 120 MV VAC GW represents the perfect balance of racing engineering and high-level comfort for on-piste skiing. Developed directly from Fischer's extensive World Cup DNA, these boots have been crafted for technical, demanding skiers who require unrelenting edge-to-edge response in every turn but need a bit of extra interior room to avoid pinching or circulation issues.

The core foundation of this model lies in the medium volume last (MV - 100 mm), engineered to naturally accommodate standard-width feet or slightly higher insteps, effectively eradicating premature fatigue without compromising lateral support. This is seamlessly paired with the revolutionary VACUUM shell technology, manufactured from the exclusive Vacu-Plast compound. This system allows the outer shell to be fully heat-molded to fit the unique morphology of your feet down to the millimeter, solving common pressure points around the ankles or metatarsals. Furthermore, Vacu-Plast stands out for maintaining its stable elastic properties in extreme cold, preventing the boot from becoming excessively rigid and uncomfortable during harsh winter days.

Technical efficiency is boosted by the Soma Tec architecture, which respects the natural "V-position" of the feet, enabling you to steer your skis with surgical precision with significantly less strain on your knees. On the inside, the 3D pre-shaped RC4 Performance MV liner holds the heel immovably in place, optimizing energy transfer and maintaining an ideal foot climate. Rounded out with the customizable Grindable Tongue, micro-adjustable aluminum race buckles, and revolutionary GripWalk soles, the RC4 120 MV is the ultimate premium tool to dominate the slopes with absolute authority, confidence, and well-being.
