Fischer RC4 The Curv GT 105 Vacuum Walk Women 65674821

The Fischer RC4 The Curv GT 105 Vacuum Walk Women is a women’s alpine ski boot that combines a stiff shell for carving with a built-in walk mode—hence the “Vacuum Walk” name—to make moving around in boots on flatter sections less of a chore.

With a 96 mm last and low-volume profile this boot offers a snug, performance-oriented fit that delivers quick feedback at the ski. Its flex rating of 105 strikes a balance between firm support for dynamic turns and enough give to stay comfortable throughout the day. At about 1.8 kg per boot in size 24.5, it remains reasonably light for its level of rigidity and precision.

In simple terms, a flex rating of 105 refers to how stiff the boot is—higher numbers mean a firmer shell that responds more directly to your leg movements. The 96 mm last measures the width across the forefoot; a narrower last provides more precise edge control but calls for a closer fit to your foot shape.
