The Scarpa Freedom Alpine Touring Boot is packed full of high tech materials and constructs. It's got patented Carbon Core, Advanced Injection, patented Ride Power Block, and Axial Power Control technologies it was toiled over by gram counting geeks. All you have to know is that it all means a lighter, thinner, stronger, stiffer, torsionally rigid, and super powerful downhill machine. The Overlap closure system delivers a gap free fit for optimal energy transfer, which also translates to power. No doubt about it, this freeride boot is light as a feather and friction free on the hike and a beast on the descent. Do you really need to know that it was over molded a carbon fiber frame to achieve this' Well, now you do. An anatomic 101 millimeter last gives your foot some wiggle room, nice for the climb, and features Axial Power for lateral stiffness and control. The instant fit FR liner boot is molded to the shell and shaped to the last for seamless fit and performance. This precise fit adds to the warmth this liner provides, which you'll notice on those scenery loving breaks on the summit. The Ride Power Block allows a 27 degree range of motion on the hike and locks down securely for a fearless downhill. Vibram's Mountain Piste sole fits all alpine bindings and is interchangeable with an AT compatible sole optional. The Freedom and Freedom SL make up Scarpa's hard charging freeride line.
