Puma x Jil Sander K-Street Sneakers Matte Bronze The new PUMA and JIL SANDER K-Street design builds on a shared foundation of purity, precision, and purpose, advancing the partnership with a new expression of movement and form. Designed under the direction of Simone Bellotti, K-Street translates a refined footwear philosophy into a streamlined sneaker. Defined by a close, contoured fit and an ultra-thin sole, the silhouette follows the natural lines of the foot, balancing softness with tension.
