The problem I noticed with quad canes were that you could trip over the feet that stick out on the sides of the cane. I still think they're a good cane tho. Almost bought one when I went cane shopping last month, but decided on a regular cane because I didnt think I was that far gone to need a quad cane.

Good thing about the quad cane is that they're probably not going to tip over as easily to where you're constantly trying to bend over without falling to pick the cane up.
