Forget long queues at the lift, forget boots that are too soft on the descent, forget unpleasant and slippery climbs. The K2 Aspect was developed for the backcountry and all its facets. With durability and absolute performance as a basis and a clean, clear design the result. This boot makes lines possible that you have only dreamed of. Outer boot Thought through to the last detail, the Endo™ 2.0 construction rises to the challenge and gives you a boot that scores with flexibility and durability. Endo is a completely new way of thinking about construction. The basis is an endo-skeleton made of urethane which replaces the various layers in normal construction. Compared to conventionally glued and sewn frames, the Endo structure can be flexed as often as desired and always returns to its original position and strength at the end - without sacrificing performance. This creates a permanently consistent flex and a boot that always behaves neutrally in all conditions. For ultimate grip and durability, the Vibram® Mountaineer outsole. Absolute hold is guaranteed in every situation. It is compatible with crampons and designed for the backcountry. Liner With high-density, thermoformable Intuition® Pro Foam 3D Liner and internal and external J-Bars, the liner has a precise fit and performance that meets the demands of a pro. A 3D-moulded EVA insole rounds off the liner with plenty of comfort. Lacing system With the patented BOA® Conda™ it is possible to open or re-lace the liner at any time without having to open the outer lacing. If you\'ve tried it for the first time, you\'ll wonder how you managed without it. The CONDA™ system is connected to the outer boot by a BOA® cog and wraps around the liner to keep your foot firmly in place. The focus is clearly on heel support and ankle support. You can choose how tight you want your liner laced and can conveniently adjust it individually. You can lace up the outer boot quickly and easily with the traditional lacing.
