Fischer RC4 The Curv One 130 Vacuum Walk

The Fischer RC4 The Curv One 130 Vacuum Walk is a high-performance alpine ski boot aimed at skiers who want precision and responsiveness on the slopes. Its name hints at a walking mode that makes trudging through the resort or hiking to fresh snow less of a chore, without compromising on downhill performance.

With a 103 mm last and a flex rating of 130, this boot strikes a balance between a secure, supportive fit and the power transfer needed for aggressive carving. The “high volume” designation gives extra room around the foot and lower leg, reducing pressure points on longer days, while a weight of just under 2 kg per boot (size 26.5) keeps mobility and comfort in check when you’re on the move.

The flex rating number reflects how much resistance the shell offers when you lean forward—a 130 score sits toward the stiffer end, favouring experienced skiers who demand direct edge control. The last width measures the interior forefoot space; at 103 mm it falls into a medium category that balances snug precision with enough wiggle room for comfort.
