A long time member of the Marker Royal family, the classic Duke gets an upgraded toe to create the all new Marker Duke PT 16 Ski Binding. This binding pairs the retention, release, and elastic travel that made everyone fall in love with the original, but adds a convertible toe that lets you tour in the backcountry. This new toe functions as a pin binding on the uphill and a downhill binding with16 DIN on the downhill.
