With the Atomic Waymaker Carbon 110 Ski Boot, you finally have a lightweight, full featured boot that offers an excellent blend of performance, comfort, and mobility all over the mountain. Carbon spines throughout the shell and cuff create stiffness and a smooth flex, while the 101mm last is roomy enough to keep your feet comfortable over the course of a long day. Since cold feet can ruin anyone's ski day, Atomic used its Gold liner that features 3M Thinsulate Platinum insulation throughout. To keep you comfortable in between runs, Atomic added a skiwalk mode that allows for 35 degree cuff rotation. DIN certified, rubber lugged soles are used on the bottoms to provide solid traction when you're hiking around or walking to and from the car.
