Moon Shoes

Toy companies are always on the lookout for products that put a new spin on a classic concept. The Moon Shoes were such a toy, and the trampoline was the product that inspired them (you know, that thing that causes around 100,000 injuries every year). On the surface, these appear to be harmless. They're miniature trampolines made of rubber bands that youngsters wear on their feet to allow them to leap a few inches higher, giving them the sensation of being actual astronauts jumping around on the Moon's surface. Of all, no one who has ever walked on the Moon has ever broken an ankle, but that's exactly what happens when you tie a couple of trampolines to a child's feet and let them go.

Aside from the injuries, the instruction manual for these items provided the best warnings of all time. Children were warned against jumping indoors, particularly on their mattresses, in order to generate a "double jump" effect, because you never know who tried it. They were instructed to only use them outside and on hard, flat surfaces such as a driveway or blacktop, which are excellent places to fall and break an elbow or ankle. Moon Shoes were first debuted in the 1950s and were made of metal, so it's surprising they brought them back in the 1990s to a much more litigious environment.
