The ultra-light Marker Alpinist pin binding (270 g not including brake) with extended, 30 mm adjustment range for soles of different lengths. It offers everything experienced touring skiers need. Its construction allows active length compensation without affecting the ski’s flex. A very stiff, ISI front (Intuitive Step In) makes the binding easier to step into, as a wide footprint with integrated stop automatically positions and aligns your boot. Kinematically optimised pin levers then allow the pins to snap shut with just a gentle push. The heel features 0°, 5° and 9° climbing aids and can be switched quickly and easily from ascent to descent mode. A 38 mm wide hole pattern transfers power brilliantly to the edges, which means control and great steering.
