The Vector line favors expert and advanced all-mountain skiers with its combination of performance, comfort features and focus on lateral responsiveness. The tri-injection shell has an easy entry design as well as 120 flex, which can be made stiffer or softer with the Flex Stance Tuning mechanism. Double Power Booster Velcro strap with a double pulley closure system and four Spineflex buckles with a flexible element help create an even wrap around the foot.
