Abstract: Disclosed is a treadmill device providing a cushioned layer of sand to walk upon. The device comprises a base having a conveyor walking surface and an underside sand storage area. The base connects to an upstanding support having a control interface to establish the walking surface speed. A second sand conveyance means draws collected sand from the lower storage area and dispenses a continuous and uniform volume of sand onto the leading end of the conveyor walking surface. The sand is then leveled to a defined depth and conveyed toward the trailing end of the walking surface. Sand is collected along the sides of the walking surface and along the trailing end thereof, whereby the sand is recollected and conveyed again to the walking surface leading end for reuse. The sand is then treated by high intensity light to prevent bacteria from forming in the sand over long periods of non-use.
