Fifty-Fifty shell

The Fifty-Fifty outer shell of the boot is designed using two separate pieces of material in the ankle area. The benefit of this feature is that when the boot is flexed forward the two pieces slide smoothly improving flex and removing the spreading of the boot in the tongue region.

Techno Spine

This reinforcement of the rear portion of the boot is not visible from outside,but its contribution can be felt.  It is made using a seamless 3d plastic inset that improves durability and provides support.  It is shaped for optimum flex and the reduction of pressure points.

Re Grip Outsole

An extra EVA shock absorption layer enhances impact dampening while superior traction produces steady footing in even the iciest conditions.
