The adidas EQ21 Run 'Black Magic Grey' combines lightweight performance with earth-friendly materials. The black engineered mesh upper, made in part with recycled content generated from production waste, features targeted zones of breathability and support. The sock-like design is bolstered with a midfoot cage and external heel counter, both of which are built with molded TPU in a slate grey finish. A full-length Bounce midsole provides springy cushioning with each stride.
