~La Sportiva Says~ 

Boot is new with tags and has never been skied. 

The Kilo is designed for the most demanding ski mountaineer, conceived and developed for maximum uphill lightness without sacrificing downhill performance. The shell and cuff are both made of Grilamid Bio Based LF Carbon™, an innovative material for this product. The new Force™ shell closure system allows you to best distribute pressure and regulate the fit on the foot. As for the rest, every detail has been developed to be functional, simple and minimal, tipping the competitive scales at just 1000g!
