High performance in a medium flex, the new K2 Spyne 120 ski boot bridges the gap between the 130 and 100 flexes in the K2 Performance Collection. Designed with the advanced skier in mind, the smooth flexing Spyne 120 drives skis with power and finesse. Now available with optional USB rechargeable Thermic® heat technology built in to the LuxFit PRO liners, cold, numb toes no longer keep you from skiing until last chair.

  • Energy Interlock: a rivet free technology that locks the cuff and lower shell giving the boot a smooth linear flex
