5 out of 5 on stiffness. That's why the Men's T1 tops the list for all-terrain performance among K2's snowboard boot collection--and it's also one of the reasons that this boot is one of our favorite picks this season. The other reasons center on comfort, adjustability and excellent value, especially when compared to other snowboarding boots at the same price. K2 balanced all that pro-level rigidity with comfort features like a Control Foam 3D Intuition liner made from high-density, thermo-forming Ultralon foam. This insulating material is flexible and durable, but what Ultralon does better than other competitor liners is resist packing out--that's the ever-expanding phenomena where repeated use stretches the sizing of your boot liners until nothing fits as well as it did when you wore the boots for the first time on the mountain. This season K2 optimized the heel hold systems in all their boots and the T1 snowboard boot offers the newest internal and external J bar configurations for full body reinforcement. The 3D formed tongue is made from similar materials, but has a micro articulated cuff. The liner uses the K2 Boa CONDA closure adjustment system that gives you near-infinite adjustment settings. On the outer shell you'll find a standard lace closure, giving you the freedom to cinch up the liner or the shell--or both at once when complete precision and power transmission matter most. Beneath everything you'll find a Vibram Super Light sole with K2's Harshmellow padding. Clever marketing names aside, this is a practical, shock-absorbing cushion in the heel and forefoot regions that helps soften hard landings without robbing you of the tactile feedback from the snow surface beneath your snowboard. If you're looking for great performance at a reasonable price, the K2 Men's T1 snowboard boot should be at the top of this season's shopping list.
