The clean-cut Yabisah SPZL, for instance, is based on the Austrian-made version of the vintage adidas Ibiza, with subtle differences achieved through chalk white lining and a contrast swivel pad one the outsole. The Stapfen SPZL, meanwhile, is based on the adidas Tramp that first released in 1972, sitting right at the intersection between a leisure shoe and a trainer. With the Warzawa SPZL, Gary Aspden aimed to create a new “City Series” style, with the intention of respectfully paying homage to the series' ancestry. The trainer features the same low-cut, terrace-focused aesthetic you’d expect, with the point of difference achieved through a flared, rather than the usual “T”, toebox.
