About this product
Black White captures the contrast between the dark and light tones of Core Black Cloud White. The adidas Breaknet 3.0 is made for youth, with this 2025 edition featuring a synthetic upper. Manufactured materials offer an alternative to natural hide, though their specific texture and care depend on the finish. The neutral palette works with blue denim, grey trousers or brighter colours, leaving room for clothing to carry more of the colour. Its appeal here rests on a straightforward opposition of black and white.
