The Able Self Standing Cane Base has a patented stand alone tri-pod base design that provides enhanced mobility and maneuvering over such terrain as sand, pavement, grass, stairs, and gravel. One of the best features of this item is that it it will stand up all on its own, alone by itself without any support. The self standing cane stand stays right in the upright position, so you can have a free hand, or put it down without having to lean it against something. This is extremely convenient and gives you more freedom.
