About this product
Black and Carbon bring a dark, understated combination to the adidas Speedex Ultra. These two tones keep the colour palette focused, with their contrast coming through in the difference between black and carbon. The Speedex Ultra name gives this adidas style its own identity, while the restrained colours keep the overall impression simple and direct.
