About this product
A textile upper gives the adidas Crazyfast.3 FG a fabric-based construction, bringing the material's woven or knitted character into focus. This youth model belongs to the X Crazyfast line and appears here in Core Black as part of the Nightstrike Pack. The 2023 edition keeps its colour palette dark and restrained. Black works with a wide range of clothing colours, from similarly dark shades to white or brighter tones, making the colour choice versatile without needing an elaborate combination.
