The collaboration between adidas, Pharrell Williams' streetwear label, and Billionaire Boys Club resulted in the 2019 Pharrell x Billionaire Boys Club x NMD Human Race Trail 'Blue Plaid.' This distinctive model showcases a striking blue and black plaid pattern, with Pharrell Williams' iconic 'HEART' and 'MIND' text elegantly adorning the left and right shoes. The innovative design includes a compact lacing system, featuring boot laces securely fastened by plastic overlays on the rear panel. Additional branding from Billionaire Boys Club graces the rear, and the sneaker rests on a Boost midsole paired with a revamped Trail outsole. The fusion of style and functionality makes this collaboration a unique and noteworthy addition to the sneaker landscape.
