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.
