For Fall 2025, Stella McCartney introduces the S-Wave Sport, a sneaker blending vintage runner aesthetics with cutting-edge sustainable materials. The upper is crafted from Piñayarn, a yarn made from pineapple leaf waste that requires no additional land, water, or pesticides, preventing up to 6 kg of CO₂ emissions per kilogram of yarn. The sole, made from compostable and recyclable BioCir Flex, features a naturally sweet twist: it is scented with cinnamon thanks to a natural dye. A statement of style, innovation, and sustainability.
