The K2 Recon 100 is one of the lightest 100 flex boots on the market. By combining four different TPU's with an optimal shell wall thickness to construct our all-new Powerlight shell, we've engineered the Recon 100 for comfort and 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. We've raised the bar in alpine boot performance and proven that LESS IS MORE.?
