Teeter Hangups inversion boots, slightly scuffed but still in great condition. The padding is still great.
Use with a chin-up bar (use one that screws into the door frame for safety), and use a small stepladder to help get into position (three steps is fine).
These "boots" are great because they take up waaay less space than a full inversion table. You do need to be in halfway decent shape to use them, though. If you are significantly overweight, get an inversion table instead.
