About this product
Black and Reebok Gum give the Reebok Nano Zero a two-tone look without relying on bright colour. The restrained combination can sit alongside a wide range of clothing colours, from greys and whites to stronger shades. Made for men, this version uses a Flexweave upper. The Nano Zero name keeps the description simple, while the contrast between black and gum gives the shoe its most noticeable visual detail.
