Representing a partnership between adidas and Pharrell Williams streetwear label, 2019's Pharrell x Billionaire Boys Club x NMD Human Race Trail 'Blue Plaid' sees the popular model decked out in blue and black plaid, with Williams' signature 'HEART and 'MIND' text on the left and right shoe. A unique, compact lacing system features boot laces locked down by plastic overlays on the rear panel. BBC branding hits the rear as well, and the silhouette sits atop a Boost midsole and revamped Trail outsole.
