The quad cane model provides increased stability for those who are able to ambulate with a single hand walking aid. Four-prong legs with anti-slip rubber tips provide increased assistance while walking and are perfect for those with pronounced single sided weakness. The aluminum frame makes it lightweight and easy to maneuver indoors or outdoors. One thing to keep in mind with a quad cane is the bulky and cumbersome design of the 4 prongs. Some might find this more difficult to control and may be harder to use for those with poor hand grip.
