Part of the adidas Spezial Spring/Summer 2021 collection, the adidas Marathon 86 SPZL 'Shock Slime' is a visually striking iteration of the iconic running shoe, drawing inspiration from Italy's Paninaro fashion movement of the 1980s. The upper of the shoe features a vibrant yellow color, constructed with breathable mesh and complemented by tonal suede overlays. The heel tab and serrated three-stripes stand out in a contrasting navy leather. Adding a bold touch, a red topline wraps around the two-tone EVA midsole, while a high-traction rubber outsole provides reliable support and grip.
