Originally a performance shoe designed to maximize responsive cushioning, the Nike Shox R4 'Triple Black' reimagines the silhouette as a streamlined lifestyle sneaker. The leather upper has several overlays, a side Swoosh, and a matte finish. Below, the Nike Shox units add responsive cushioning under the heel, while a rubber outsole covers the forefoot. The entire shoe is dipped in black, save for a bit of white branding on the tongue.
