Exerlopers® trademark, impact-lessening running shoes mounted on elliptical springs: "The first thing you notice when wearing Exerlopers® is that you bound along like an astronaut on the moon when you're running" (Fortune).

BACKGROUND: Exerlopers® were invented by Gregory Lekhtman, a Russian-born neurophysiologist, who devised the word after searching an English dictionary for elements to denote a workout based on running with a lengthened stride. Research has shown that runners wearing Exerlopers® experience significantly less joint stress, and burn more calories, than those wearing conventional running shoes. Exerlopers® have been used in the French and Russian astronaut training programs.
