Nice Replacement for Original Glides
These work pretty well.  I was able to install them without removing the leftover portion of some Drive ball glides (these look like regular tennis balls but fasten around the walker leg with a hard sleeve which is difficult for me to remove).  They work well on my hardwood floors without scratching.  However, they do have a tendency to slip around on the leg, though I've had no problem with their coming off.<br /><br />I've not tried them outside on the sidewalk for fear of scrapes that would cause them to scratch the floors.  (Both the original glides and the Drive ball glides were destroyed by two visits to the sidewalk.)
