TECNICA MEN'S MACH SPORT HV 100 SKI BOOTS A ski boot that fits well is the key to enjoying a great day on the mountain with your family and friends. The Mach Sport HV 100 is all about warmth, comfort and convenience, designed for intermediate skiers with high-volume feet or larger overall frames. The NFS Liner is warm and supportive, providing a comfortable out-of-the-box fit. But if needed, you can add personal customization with Tecnica's C.A.S. system to solve any additional fit problems. Double Quick-Instep and Lift-Lock buckles allow for easy entry and exit, while the 100 flex strikes the perfect balance between comfort and performance, allowing you to happily ski until the lifts stop spinning. Testers proclaimed the Mach Sport HV 100 to be a high-performing, high-volume boot that skis like a much more expensive boot. It enveloped tester's feet like a hug from an old friend but had solid edge-to-edge performance on the hill. Testers noted it would be a great option for an intermediate skier ready to step it up a notch this season but keep his feet in something comfy. TECHNICAL SPECS Customization Liner: N.F.S.
