The adidas Ashurst SPZL 'Grey Yellow' is part of adidas' Spezial Collection for Spring/Summer 2020, which is curated by Gary Aspden and draws inspiration from the Northern Soul movement that dominated British club culture during the 1970s. This sneaker takes design cues from the adidas Sydney, a popular city running shoe. Its upper is made of grey nylon and features a breathable mesh toe box, while the quarter panels sport vibrant yellow leather three-stripes. The vintage look is further enhanced by the netting on the foam midsole.
