I
always wondered why they have no wheels, there must be a reason but
it
eludes me. Maybe some wheels with brakes. Wh these tennis balls?


Some do have wheels, but they're for people who have fair balance and
reflexes. Wheels tend to scoot out from under old folks who lean on
their walkers the wrong way.

I think, if I were not sure of my ability to catch myself, I'd want
skids.
