Made with the help of Chitose Abe, the sacai x Blazer Low 'Iron Grey' updates Nike's earliest basketball shoe with a doubled-up construction. The shoe's upper is built with suede, finished in Iron Grey and overlaid by dual eyestays, laces, Swooshes and tongues, which themselves sport dual tongue tags, once of which has co-branding. An exposed-foam collar adds to the aesthetic, while various overlays climb up from the midsole. The midsole itself is built with rubber, giving way to a rubber outsole underfoot that incorporates a herringbone outsole for traction.
