UltraBoost 4.0 'Breast Cancer Awareness'

To promote breast cancer awareness, adidas released this UltraBoost 4.0, featuring a Primeknit upper woven with a blend of black and white yarns. A similar two-tone design is used on the laces, while the TPU cage and heel counter are coated in matte black. Underfoot, a black Boost midsole is contrasted by a crisp white rubber outsole. The neutral design is accented on the heel with a pink ribbon, the international symbol for breast cancer awareness.
