Fischer RC4 100 HV VAC GW Ski Boots (U09223)

In the motoring world, the best Gran Turismo (GT) cars not only offer a capable engine and spacious cabin but also allow the suspension and seating ergonomics to be tailored to the exact measurements of the driver. The Fischer RC4 100 HV VAC GW applies this sophisticated engineering to the snow. Its "bodywork" features a High Volume (HV) design starting at a 102 mm last. However, because it is crafted from Vacu-Plast polymer, the entire chassis can be heat-molded in-store. This process traces the anatomy of your foot, creating a custom cabin that eradicates pressure points without losing the hold necessary for sporty driving.

The "suspension" is calibrated with a 100 flex. This is the perfect tune for progressing and advanced skiers: firm enough to confidently drive the edges at high speeds, yet elastic enough to forgive technical errors and absorb vibrations from rough terrain without punishing the joints.

To complete this high-performance and comfort package, the boot is fitted with GripWalk (GW) "tires." These textured rubber soles with a curved profile facilitate a natural rocking motion, transforming your walk over ice, stairs, or the parking lot asphalt into a completely safe and fluid stroll.
