An icon of the running world for over 20 years, the Adizero family serves as the inspiration behind these adidas Adizero Aruku shoes — specifically the famed Adizero PR. Roll through your day on the radically curved rocker midsole that smooths every transition between heel strike and toe-off. Innovative Swirlfoam cushioning infuses nitrogen into the foam for a superior sensation with precisely placed reinforcements — a true revolution in comfort. Upper details hook back to the heritage model, with comfort details like a soft lining and synthetic suede tongue.
