Nordica Speedmachine 14 Ski Boots - Used 2008: The Nordica Men's Speedmachine 14 Ski Boot's stiff 130-120 flex helps you drive and turn your skis with precise control, so you're aggressive ski style won't land you in a tree well. The Speedmachine flex adjuster has two modes—the hard mode handles tight turns on ice and hard-pack, and the soft option gives you more flexibility for off-piste descents. The thermo-moldable liner and bi-injected design gives your feet total support throughout your turns and keeps your feet comfy, so they don't feel like they've been squeezed in a vice all day.
