The Stella McCartney x adidas women’s Treino Mid ‘Collegiate Navy’ delivers the British fashion designer’s stylish take on a performance training shoe. Contrast stitching and an oversized scarlet floral print enliven a navy textile upper made with recycled polyester. The mid-top is mounted on a full-length Boost midsole, its sidewalls wrapped in a navy TPU cage for enhanced stability and support. Underfoot, a gum rubber outsole provides grippy traction.
