Year Released: 1986

Another adidas shoe with another form of adjustable cushioning — for a period in the mid-'80s, adi appeared to be making things up as they went along. And maybe they were. The APS used a proprietary key to adjust the spacing of rods in the midsole, which in turn firmed or softened the cushioning. There is probably a reason that these systems fell by the wayside, but they're still awfully cool to look back on.
