The new Apex XP Antero is a great option for the strong skier who has been searching the perfect fit with a ski boot that is packed with power. The new Nanolite Carbon Chassis reduces the weight of the external frame by 20% without any compromise to the performance. A Dual Stack Boa Closure System gives you the ability to fine tune the fit, both in the cuff of the walking boot and the cuff with 20 points of closure. The XP Antero is still able to be easily dialed in for your biomechanics with three different flex settings, four different forward lean positions and a dual cuff alignment adjustment. The liner of the Apex XP Antero features a fully customizable heat moldable foam. To round out the total package of comfort, Thinsulate Insulation has been added to the walking boot to keep you extra warm on those nasty cold January days.
