Ideal for women all-terrain riders who want a snowboard boot with a medium amount of flex, the K2 Haven Boa Coiler offers easy entry convenience with a single-pull closure. This boot is a great design for women who make the most of their riding time but still want a practical balance of comfort and performance features. The K2 Women's Haven Boa Coiler features 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. Now the Haven Boa Coiler features new internal and external J bars and full body reinforcement. The Boa Coiler system is actually a partnership with the Boa Company, and this H2 Coiler closure has an integrated, low-friction reel that smoothly retracts and retrieves your adjustment cables so you can lock in the fit and focus on your riding. Along the footbed you'll find 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. This season K2 also reduced the sole weight on all of the snowboard boots, including the Women's Haven Boa Coiler, so you're closer to your snowboard while still enjoying excellent traction on almost any frozen surface.
