The K2 LUV 100 and Luv 100 Heat are designed to be the most versatile performance women's alpine boots on the market today. By combining four different TPU's with an optimal shell wall thickness to construct our all-new Powerlight shell, we've engineered a boot designed for elite performance with the lowest possible weight. Stiffer PU is strategically placed where boot meets bindings and along the spine of the boot for immediate power transfer, and medium and softer PU surrounds the body of the foot and near the instep to dampen vibration for ease of entry. The shell is fully TPU heat moldable so you and your boot tech can dial in the fit to your specific foot features. The FastFit instep entry feature helps the boot slide off and on with ease. The outsoles can be canted in 0.5 degrees increments up to 3 degrees to match your body's natural stance. And the women's specific adjustable cuff allows for the perfect fit regardless leg length or calf shape. To top it off, we offer the LUV 100 with or without Thermic® heated liners for toasty toes on even the coldest days because we know that warmth isn't just comfort, it's performance. Available in two widths/lasts, 98mm and 100mm.
