In 2017, the Contrast Stitch pack of the women's NMD_XR1 sneakers included the Trace Blue color option, alongside three others. These shoes sport tonal mesh uppers, which are complemented by understated contrast stitching around the ankle collar that perfectly matches the outsole. The Trace Blue variant specifically boasts a coherent tonal style, with a blue upper and a white Boost midsole, accentuated by white contrast stitching for a touch of visual interest.
