So how does it work, anyway? Basically, this quality tip consists of a large hollow sphere (two inches in diameter) with an encased stainless-steel roller bearing. Its hook-on style provides for easy attachment to any of our folding white or kiddie canes. The rolling tip is lightweight and simple to maneuver, and easily handles road obstacles and cracks in the pavement.
This roller tip truly makes cane travel a lot easier - and much less tiring, too (as you don't have to keep lifting and tapping the cane). Most users agree it's well worth the price!
