Yes, you too can be "a Spaceman or Hopalong Casually." How casual is this, to be bouncing along the sidewalk in your Space Shoes? It will soon be followed by your casually falling on your face.
These mini-surfboard-and-springs devices are strapped to your regular shoes and will keep you hopping for the proverbial "hours of fun."
I've always wondered, precisely how many hours are "hours of fun"? I think it probably translates to "about five minutes or less."
Please note that all you fun-loving Canadians will have to shell out $2.75 instead of $1.98. That's just the way it is. Too bad they can't just lob them over the border - I'm sure they are springy enough.

I would guess that the Space Shoes ad is from the 1960s. In the 1960s, Murray's in New York made "sensible" shoes called Space Shoes (I didn't find a picture, but I'll bet you can imagine them) - and then there were these exquisite Outer Space Shoes from 1973. To go with the Lesiure Spacesuit, no doubt (medallions not included).
I have no idea why they are called Outer Space Shoes. Maybe that's the only place you'd be in fashion when you wore them. Those white ones with the buckles in particular.
Many thanks to
tomheroes for the springy Space Shoes ad. The Outer Space Shoes are from
The Rotarian, April 1973.
