Designed in collaboration with the UK-based retailer, the size? x LXCON 94 'Carstensz' gets its name from Indonesia’s Carstensz Pyramid, rated one of the world’s most difficult mountains to scale. adidas’ retro-inspired runner features a beige Cordura fabric upper, with white leather overlays and contrasting Active Red accents throughout. A molded EVA midsole with adiPRENE cushioning is supported underfoot by a gum rubber outsole.
