A sliding device provides a binding-free apparatus suitable for trick and other riding on snow, sand, ice and other surfaces. An elongated deck to support the rider is elevated from and attached to an elongated runner, which provides a surface that slides on the snow, sand, etc. The runner may be made more narrow than the deck to provide leverage for the rider to tilt the device onto an edge of the runner to steer the device. The device may not have any defined front or back portion and thus be adapted for riding in either direction.
