The Atomic Live Fit 70 W is designed for the true beginner to intermediate skier who has a medium to wide forefoot, medium to wide leg shape, and a tall instep. Atomic has placed two soft rubber panels on the inside and outside of the foot that will stretch as soon as you set your foot inside the boot to keep you supported or comfortable. The hard shell of the Live Fit 70 measures 102mm, but the soft rubber panels accommodate feet much wider than that. The Live Fit Panels also help keep your feet warm due to the fact that the rubber panels do not transfer cold temperatures the way that plastic does. The two Mega Buckles are micro adjustable, and easy to close. The upper buckle has a macro adjustable slider that can easily be moved out to accommodate the fullest leg shapes. With a flex rating of 70 the Live Fit 70 will allow a true beginner to flex the boot, but it also has the rigidity to offer control to the solid intermediate skier. If you have heard horror stories about ski boots, and you are new to the sport, or a novice who needs comfort for wide feet, the Atomic Live Fit 70 W is the way to go!
