Desk Treadmill that folds

I am lucky enough to work for a company that provides me with a sit down/stand up desk. My entire desk (L Shaped with over 8 feet by 2 feet of space) goes up and down so everything stays ergonomically correct. I am thinking about adding an under desk treadmill for use when I am standing. Does anyone know of a compact treadmill that can be tucked under a desk but will still fold up when not in use?
