With an accommodating 100mm last and forgiving yet performance driven 110 flex, the Nordica Men's NRGy Pro 3 Ski Boot is ideal for the intermediate to advanced skier seeking a comfortable yet hard charging pair of boots. With the NRGy series, Nordica has developed a line of boots that are easily customizable to enhance both comfort and performance. Utilizing a Custom Cork Fit liner, which is heat moldable, you can finely tune the fit of these liners to match the shape of your foot. The benefits of cork are two fold: first, it is an excellent insulator, so your feet stay warmer on those extra cold days secondly, due to its density, it doesn't compress as you lean into a turn. That means an increase in power transmission and a more responsive feel from your boots. The BBF Boot fitter design utilizes screwed parts to make custom boot fitting easy. High traction soles are nice when you're lugging your gear to the ski lift, and they help to prevent you from taking a slider on the deck of the lodge. Meanwhile, the pinned performance cuff and high performance hinge both offer a bomb proof connection between the cuff and lower shell that results in precise energy transmission and a dependable feel both coming in and out of a turn. Nordica also introduced an all new system within the shell to prevent snow and moisture from seeping into the liner to prevent cold and wet feet. Four high quality aluminum buckles allow you to dial in the fit you want, and the power strap provides that extra bit of umph you need when busting through chopped snow and crud.
