FISCHER RC4 105 LV VAC GW Women's Ski Boots (U05423)

The Fischer RC4 105 LV VAC GW represents the perfect choice for advanced and expert female skiers who demand the handling and control of a high-level technical boot, but prefer a slightly more forgiving 105 flex that reduces fatigue without sacrificing responsiveness. Engineered under the rigorous standards of Fischer's race DNA, these boots deliver a pure, instant connection to the skis, entirely eliminating power transfer delays due to their tight low-volume last (LV - 98 mm), which has been developed leveraging the innovative Fischer Scan-Fit® technology after analyzing hundreds of thousands of customer foot scans.

The outer shell is manufactured from the exclusive Vacu-Plast polymer, an advanced material that reacts uniformly to extreme cold, ensuring that the 105 flex rating remains consistent and elastic throughout the winter. The definitive advantage of this model lies in the VACUUM customization technology, which allows professional bootfitters to thermally shape the outer shell to solve common pressure points around the ankles, instep, or navicular bone, guaranteeing an impeccable, custom-made fit. Furthermore, it incorporates the Adjustable Forward Lean system, a mechanism that adjusts the cuff angle by 3 degrees to easily switch between a neutral comfort stance or an aggressive attack position to carve into turns.

On the inside, the iFZ Performance liner features a specific cut that respects the lower morphology of the female calf muscle and is endowed with top-tier Primaloft® insulation to ensure exceptional all-day warmth and moisture protection. Its Individual Fit Zone (iFZ) system via outer velcro material allows for attaching additional customization pads to increase heel hold or mitigate friction. Additionally, the boot boasts a Grindable Bootboard for precise height adjustments by a specialist, a premium velcro strap, and revolutionary GripWalk® soles that transform walking through the resort into a safe, natural, and highly comfortable stroll. The RC4 105 LV is the definitive premium tool to dominate the slopes with absolute authority, confidence, and well-being.
