This collaborative take on the NMD Human Race Trail features signature design details from Pharrell’s Billionaire Boys Club brand, including ‘Heart’ and ‘Mind’ embroidered on the multi-color vamp of the one-piece knit upper—a reference to the BBC tagline ‘Wealth is of the heart and mind, not the pocket.’ A gold foil ‘B’ adorns the red leather heel tab on the left shoe, while the right features adidas’ trefoil logo.
