Originally released in 2000, this 2019 remake of the Shock R4 is finished in the OG black and metallic silver colorway. The build is true to the original, highlighted by molded metallic silver paneling with black leather trim around the toe, eyestay, and heel. Contrasting pops of red are most noticeable on the Nike Shox pillars at the heel, delivering a literal bit of spring with each step.
