In 1971, Oregon track coach and Nike Co-founder Bill Bowerman used his wife's waffle iron to experiment with the idea of using waffle-ironed rubber to create a new sole for footwear that would grip but be lightweight; hence making easier for individual's to be able to increase their speed. Oregon's Hayward Field, where he worked, was transitioning to an artificial surface and "Bill wanted a sole without spikes that could grip equally well on grass or bark dust." He was talking to his wife about this puzzle over breakfast, when the waffle iron idea came into play.  Bowerman's design inspiration led to the introduction of the so-called "Moon Shoe" in 1972, so named because the waffle tread was said to resemble the footprints left by astronauts on the moon. Further refinement resulted in the "Waffle Trainer" in 1974, which helped fuel the explosive growth of Blue Ribbon Sports/Nike.
Like most electric waffle irons, the Cuisinart WMR-CA waffle maker isn't meant to be submerged, and the waffle plates are built right into the machine, so you can't remove them for a good scrubbing. Surprisingly, removable plates are relatively rare, especially in the American/traditional waffle maker category. But the Black and Decker G48TD (Est. $40) has them, which makes it very convenient to use. Not only do the non-stick waffle plates pop out for easy cleaning, they also have a completely flat reverse side (also non-stick). Flip the plates to their flat side and open the G48TD's lid all the way, and you have yourself a mini griddle for cooking things like pancakes and bacon; or close the "floating" hinged lid and use it to toast sandwiches.
