These wore out within a couple of weeks. Before I knew it my walker was scraping the floor with bare metal sticking out through the bottoms of the tips. Maybe no walker tips can deal with city sidewalks, and maybe all walker tips need to be replaced after a couple of weeks. These are so hefty up top, where it doesn't matter, and so light at the bottom, where extra rubber is needed. Maybe I need to try tennis balls?
