British sneaker retailer size? has collaborated with Reebok to bring a change so subtle to its Instapump Fury silhouette that you might not notice it upon first glance. That change is the use of a new circular knit technology in the construction of the upper underneath The Pump system. The result is a bespoke patterned weave on the underlay, resulting in a hazy, mesh-like texture that sits in contrast to the clean, futuristic air bladders. Available in black and white colorways, the size? x Reebok Instapump Fury is available online and in-store from April 29 for £129 GBP (approximately $188 USD).
