Nordica's GPX family is all about all mountain domination, from the burliest GPX 130 to the most mellow GPX 100. Sitting right in the middle, the GPX 110 Men's Ski Boot balances fit, power, precision, and comfort, so you can ski hard from bell to bell without spending half the day sitting by the fire coaxing your toes back to life. Although the GPX 110 has, as you might've guessed, a middle of the road 110 flex rating, its relatively narrow 98mm last provides a snug, fairly aggressive fit that makes railing corduroy, skipping through bumps, and zipping between trees exercises in fun, not in terror. The Race GP Primaloft heat moldable liner hugs the contours of your foot for comfort and precision, and the Full Shock Eraser bootboard takes the sting out of jumps, hardpack, and bumps so your feet absorb less punishment. Made of PU, and the cuff and shell provide a firm and consistent flex in all temperatures, and Nordica gridded the shell with its Bootfitter's Best Friend system, which makes it easier for bootfitting experts to punch and grind the shell to your exact specs. While the performance of the boot is awesome, comfort is really the GPX's calling card. It has canting and flex adjustments, so you can personalize the fit, and all the hardware attaches by screws instead of rivets, so full customization is much faster and easier. GP dual articulating buckles make opening and closing the boot super simple, and the Intuitive Easy Entry instep panel is softer than the rest of the boot, so no tears need be shed while you're trying to get your chilly boots on in the morning. Nordica also integrated its Full Motion Pivot, which allows increased customization around the ankle, and topped the GPX off with replaceable Extra Grip soles for easier hiking and smoother parking lot navigation.
