A heel unit including a base comprising a fastening arrangement for fastening to a gliding board, a binding body, and coupling means arranged on the binding body. The coupling means engage with a heel portion of a gliding board boot in a downhill position of the gliding board binding to securely hold the gliding board boot on the gliding board binding. The coupling means protrude in a longitudinal direction from the binding body in the downhill position. The heel unit includes an Mz release mechanism to preload the coupling means into the downhill position so that, in the downhill position, the coupling means are freed from engagement with the gliding board boot upon action of a force exceeding a predetermined release force, and so that the coupling means move from the downhill position into a release position via rotational movement of the binding body about the release axis of rotation.

A ski shoe harness includes a sole, a receiver, and a heel strap. The sole includes a binding mechanism adapted to engage a binding system of a ski. The sole and the receiver are attached and define a space to receive the front portion of a shoe. The heel strap, attached to the receiver, wraps around the rear portion of the shoe, interlocking the ski shoe harness with the shoe. Further, the heel strap includes an adjustment mechanism. Using the ski shoe harness of the present invention, non-ski shoes and boots of a various designs and sizes may be used to share and utilize skis having common cross-country binding systems.
