A toe unit for a safety ski binding for disposal on a horizontal surface of a ski includes a base adapted to be mounted on the ski, a bolt having a lower end and an upper end, and a mounting portion for mounting the lower end of the bolt to the base. The mounting portion permits axial movement of the bolt between a first position and a second position, and secures the bolt substantially perpendicular to the horizontal surface of the ski when the bolt is in the first position. The mounting portion also permits pivotal movement of the bolt about a location on the base when the bolt is in the second position. The toe unit also includes a sole contact portion attached to the bolt for retaining a sole of a boot and for moving the bolt axially from the first position to the second position in response to a predetermined force exerted by the boot in a direction away from the base.
