In 1986 PUMA debuted the quaintly named RS Computer, a cutting-edge running shoe with a built-in pedometer that measured distance, time and calories burned. After a run, users could download the pertinent data with an actual cable, linking the sneaker to the game port connector of their Apple II. Decades later, PUMA ditched the hardware and reintroduced the Luddite-friendly version of the shoe as the RS 100. Previewed at PROJECT Las Vegas, the vintage silhouette is set to make a strong showing in Fall 2013 in a variety of unique colorways, highlighted by a neon hued number featuring zebra stripes at the heel and toe box.
