Wikisimpsons - The Simpsons Wiki
Assassins are a sophisticated type of running shoes with Velcro straps, a water pump on the tongue, reflective side walls, and a retail price of $125. Ned Flanders owns a pair, as did Homer Simpson before his was destroyed by Santa's Little Helper. Also they can be personalized, with a name engraved on the back of them, which Ned had. They beep when the heart beat rate drops while exercising.
