F1 is the boot for all alpine touring skiers. The state of the art in terms of lightness, comfort and performance. F1 is suitable to all alpine touring activities, great for going uphill with crampons while performing equally on the downhill, ploughing through fresh snow. The Carbon Core Technology on the shell and the X-Cage Evo on the cuff offer great stiffness and improve the transmission of impulse to the ski. The new ski/walk mechanism allows an easy and safe transition from ski to walk with minimum volumes. Only two closure systems for a fast fit: the BOA® and the Fast Buckle with reference graphics.
