In this Article When famed designer Steven Smith, then a Reebok employee, crafted the Instapump Fury back in 1994, he changed the world of running footwear forever. Since then, the Instapump Fury has become a cult favorite worldwide — especially so in Asia — found a place in the Design Museum of London, and even been reworked by high fashion houses like Chanel and Maison Margiela. Its most famous colorway is the OG “Citron,” a bold mix of neon yellow, red and black, and now the “Citron” is coming back for the first time since March 2019. As you’d expect, this re-release is true to the original: details like the neon yellow Pump bladder, black mesh upper and rich red detailing are left largely unchanged. This 1-of-1 ethos is continued on the two-piece midsole, held together by a carbon fiber plate under the wearer’s midfoot and loaded with springy DMX cushioning in the heel. A signature black Pump system on the tongue plus bold Reebok branding on the heel and forefoot alike round off the look.
