K2 Contour Snowboard Boots - Women's Exploration: Day In and Day Out The most supportive boot in our line of snowboard boots for women and favored by the Alliance(TM), the Contour packs a ton of tech into an attractive package. Comfortable charging lines and railing turns, this boot is packed with our BOAA(R) Conda(TM) liner lacing system and Endo(TM) 2.0 upper, making for a snowboard boot that pushes the boundaries just as hard as you do. Key Features: H3 BOAA(R) Coiler Lacing - A cable and reel based lacing system that creates even tension and easy lacing operation. This system features low friction guides for even tightening. BoaA(R) Coiler works to automatically retract lace slack so your boots stay nice and neat. Flex Zone Upper with Endo(TM) 2.0 BOAA(R) Conda(TM) Liner Lacing - A patented K2 liner lacing system that uses a urethane harness to gently hug your ankle, creating unrivaled heel hold. BoaA(R) Conda(TM) allows for adjusting liner tightness and heel hold on the fly from outside of the boot, even with gloves on. 3D Formed EVA Footbed VibramA(R) Pro Light Outsole - Combining the ultra grip and durability of VibramA(R) with K2's rider insight, the Pro Light outsole is lightweight and built to last.
