Abstract: A ski binding adapted for telemark and alpine touring comprises a cable retention system between the toe assembly and a heel carriage retention structure that includes an elongated plate on which the heel carriage is adapted to slide, and an adjustment carriage. A portion of the cable defines a truss configuration pivotable along the transverse axis of the binding. The heel carriage is tensioned forward by means of a biased connection extending between the adjustment carriage and the heel carriage. A heel assembly includes dual pivot points and a cam arrangement to provide a selective release set point for the heel of the boot.
