In 2011, Reebok became the official provider of CrossFit footwear and apparel, marking the introduction of the first-ever CrossFit-specific sneaker, the Reebok Nano. Designed for CrossFit programs, the Nano offers exceptional support during intense movements, weightlifting, and short-distance running. This particular version of the R CrossFit Nano 8.0, known as the 'Tin Grey' sneaker, features a Flexweave upper that provides both adaptability and strength with its unique figure-8 weave. Additionally, the shoe's sole is equipped with grooves to ensure a flexible footstrike.
