This is one of the lightest Alpine Touring boots around & will give you confidence on long ascents, & help you conserve energy for the descent. At its heart lies Axial Alpine Technology (AAT), the anatomical framework of the boot that matches the shape of the foot perfectly ensuring control & power transmission to the edge of the ski. It also has a thermo-formable Intuition liner for superior comfort & control, while the Pebax renew construction keeps weight to a minimum & gives a uniform flex. Finally, the new Cayman/ Vibram sole provides security on any terrain & its 18-22 forward lean makes long descents a bit more bearable.
