The Atomic Waymaker 90 All Mountain Ski Boots is Atomics top progressive all mountain ski boot with an instant medium fit, all mountain versatility and strength, and exceptional warmth. With a medium fit and medium flex, its perfect if youre a serious all-mountain skier but not professional quite yet. It features a stiff and super lightweight Carbon Spine that delivers maximum power transmission to the ski, plus a cuff height and liner designed specifically to fit female feet. Our Free/Lock System, which either locks or frees the cuff from the shell, will help you on your way to the best powder spots. And thanks to a Multi-Norm Chassis, the boot is compatible with all binding types on the market: switch easily between DIN, Touring and WTR Grip Pads with low tech inserts (Dynafit original geometry). Atomic has also incorporated a Silver liner with 3M™ Thinsulate™ Insulation to keep your feet warm and responsive even in extremely cold and damp conditions, plus new richer power straps.
