The NMD R1 'Tech Ink' is a unique adidas sneaker that stands out from the regular NMD R1 collection. Unlike most NMD R1 sneakers which feature a mesh upper and neoprene heel, this particular model boasts a suede heel counter. It was officially released on October 1, 2016, showcasing a core color known as 'Tech Ink,' which can be described as a darker shade of baby blue. Alongside the 'Tech Ink' version, four other colorways were also introduced, namely 'Core Black,' 'Vapour Steel,' 'Tech Earth,' and 'Collegiate Navy.' These multiple options allowed sneaker enthusiasts to choose the variation that suited their personal style preferences.
