The extension of the award-winning RX all-mountain range, the SX 100 expands our "Choose Your Width" concept to 102mm; ensuring skiers with wider feet no longer sacrifice comfort for real-deal performance. Featuring all of Lange's acclaimed fit and performance solutions, easy entry-and-exit, and a more relaxed "out-of-the-box" fit, SX offers all-day comfort with the essential, high-performance DNA generally limited to narrower, race-oriented boots.
