Apex MC-X Ski Boot - Men's: APEX MC-X- BIG MOUNTAIN PERFORMANCE - New this year, Apex is introducing this Big Mountain Performance design with exciting new color as well as outstanding performance. The MC-X can take you anywhere on the mountain that you want to go! Apex has taken a revolutionary approach to ski boot design. Their 2-part system is made up of the walkable support boot and the modular chassis. The MC-X has a Vibram® sole to give the walking boot world class climbing traction. The dual Boa Focus Closure system allows the skier to adjust the laces around the calf and ankle (using the front Boa reel) separately from the laces on top of the foot (using the side Boa reel). Skiers that require personalization will appreciate the Apex’s tunable A-Flex Suspension™, cuff alignment and micro-adjustable buckles. Bring on the Big Mountain terrain!
