The F1 GT is the ideal boot for ski mountaineers seeking an efficient yet streamlined product that’s ideal for touring with light equipment. The cuff is made of Grilamid® Fiber Glass LFT and is paired with a single buckle and Velcro Finger strap providing a great progressive flex throughout the turn. The Grilamid® Fiber Glass LFT shell features a full-length Lambda Frame for comfort and increased torsional rigidity while our new Overlap Shield Tech gaiter allows for easy entry and enhanced protection from the elements. A lower buckle works in unison with the Wave Lite Closure system for a secure, uniform fit over the entire instep without any pressure points. The F1 GT is the ultimate combination of comfort and touring efficiency in an ultralight package.
