The adidas NMD_R1 "Metallic Blue Boost" features a monochromatic white knit upper that hugs the foot for sock-like comfort. Welded three-stripes, a semi-translucent heel tab and molded eyestay all maintain the pristine design theme. The minimalist build is supported by a full-length Boost midsole, rendered in an iridescent blue finish for an eye-catching look. EVA plugs provide added stability, while a matching white rubber outsole offers durable traction underfoot.
