Step into a revolution — the easy entry and high performance revolution of our innovative Step In design. Made for skiers looking for a medium-volume fit and performance flex, the women's Rossignol Vizion 4B Pro 100 ski boots feature a ground-breaking overlap shell design that opens wide in the back for unparalleled slip-on ease thanks to an innovative spoiler and spine mechanism. The system creates wide articulation at the cuff and complete locked-in support for precise power transfer and full downhill performance with unmatched ease of use. Just slip in, buckle up and ski.
