The adidas NMD R1 'Night Indigo Yellow' updates classic NMD style with a sustainable build made with at least 20% recycled materials. Crafted from a single piece of knit textile in a dark navy finish, the sock-like upper features blue signature three-stripes and a molded heel patch in a contrasting yellow finish. The minimalist design is mounted on a full-length Boost midsole with stabilizing TPU plugs embedded in the sidewall. A navy rubber outsole provides durable traction underfoot.
