The stiff and mean Lange Men's XC 120 Ski Boot gives aggressive skiers the big ski driving performance they need to crush steep lines and stomp big landings. The stiffest offering in the XC line, the XC 120 has a stiff 120 flex combined with a wide 102mm last to accommodate those of us with wide, high volume foot shapes. The boot is built with Lange's mono injected structure, delivering the same solid performance as a classic pair of Langes, but with the addition of a walk mode to the boot, you'll be able to access those hike to lines you've been drooling over once patrol drops the ropes on them. The XC 120 has just about every feature you'll need to ski aggressively in and out of the resort thanks to the metal on metal Power V Lock walk mode. The metal on metal connection delivers a solid and reliable lock into ski mode and won't wear down after heavy and repeated use. The Ultra Grip rubber soles keep you sure footed when you're hiking rock strewn and wind hammered ridge lines, while the high traction arch pad extends the traction throughout the arch, so you won't take a slider when you high center the boot on a rock or chunk of ice. The stock liners are Lange's heat moldable, Thermofit RL3 liners with lace closure, ensuring a secure and comfortable fit that will keep your feet happy lap after lap.
