Skiers asked for Nordica's traditional four buckle performance boot back and they delivered with the new NRGy Pro 1. The Pro 1 has a 100mm last that best fits skiers with a medium to narrow forefoot and medium sized shaft of the leg. The PFP Performance Liner is made with cork, which can be easily customized by heating, punching or grinding to get your fit dialed in just perfectly. The Pro 1 has a burly 130 flex for the biggest and most aggressive skiers that will have power and rebound for both on and off trail skiing. Dual Density PU Soles are very durable, not slippery and replaceable to lengthen the life of your boots. If you are a high powered, high energy skier with a medium width foot that missed Nordica's traditional four buckle boot the Nordica NRGy Pro 1 is the boot for you.
