Gradual compression foams adapt to both narrow and wide foot shapes

Making its audacious debut in 2000, the Shox R4 shattered the mould of traditional pavement pounders. The silky smooth synthetic upper takes design cues from spacesuits and astronaut gear, with fluid ripples, laser perforations and a stance built to help propel forward motion. Four compressive columns lift the heel, offering a stable structure and bona fide bounce.
