The adidas women’s X9000L2 ‘Core Black Grey’ features a stealthy finish on a lightweight runner built with plush cushioning. The upper, constructed from ventilated knit textile with no-sew overlays for added support, rides on a full-length Bounce midsole, good for a soft landing with each step. Inside the shoe, the sockliner is made with algae-based EVA foam, resulting in liters of less polluted lake water.
