Reebok took on the role of being the official provider of CrossFit footwear and apparel in 2011, leading to the introduction of the Reebok Nano that year. The R CrossFit Nano 8.0 'Black' shoe is a result of years of refinement and optimization to cater to activities involving intense impact, weightlifting, and short-distance running. This particular version of the shoe showcases a Flexweave upper, where fibers are intricately woven in a figure-8 pattern to enhance its adaptive strength. Additionally, the sole incorporates flex grooves that encourage a more natural sensation during movement.
