The Rossignol BC X5 ski boot swaps a traditional lace-and-strap closure for a Speed Lace Lock system that tightens and locks down in one motion. Cold hands at the trailhead have less to fumble with, and the lock holds through a full day without needing to re-tighten mid-tour. What Our Gearhead(R) Experts Are Saying:"The wide Rottefella sole keeps me square over the ski when the trail buries a rock or a root under fresh snow. My ankle can still flex forward into a stride, but the cuff won't let it roll sideways when the snow turns uneven."
