Synchro is the La Sportiva ski boot dedicated to free-ride ski mountaineering. It combines power, resistance and precision comparable to a ski boot for downhill skiing, with the lightness and mobility of a ski boot of new generation mountaineering.
The Synchro structure allows you to fully enjoy the descents on powder snow relying on the perfect transmission of power and control over the skis, accentuated by the use of safety TR2 bindings (fully compatible with this model). The lightweight Grilamid shell is flexible and resistant while the patented Vertebra Technology ™ locking system loaded carbon is part of the boot structure. The perfect transmission of power is accentuated by the Booster Dynamic Power Strap®, a highly resistance elastic strap that allows flexibility and shock/vibration absorption between the shell and the skier’s leg, and the innovative hinged Double Power Tongue ™ consisting in two overlapping parts which, in ski mode, confer structural rigidity for the descent and in walk mode, facilitate the stride by increasing mobility and flex qualities. The new Buckle Pegasus Plus ™ locking system consists of 4 tough, precise buckles that allow perfect adjustment of volumes thanks to the Backbone Control micro regulation settings in a compact, functional design, created to facilitate opening / closing while containing the overall volume of the boot.
