Abstract: A snowboard step-in binding having a rotatable soleholder that can be moved between two limit positions and can be opened using an opening lever. In order to ensure a secure lock with the soleholder even with a layer of snow present, but prevent inadvertent opening, a dual-action lever with one arm designed as an opening lever and the other arm designed as a rotating lock is provided. This rotating lock is maintained by forcing two cam surfaces, which extend from a common apex and contain an intermediate rest surface, against a locking bolt by the force of a spring.
