Introducing the new KARHU Mestari Run Kesä in Chocolate Torte / Tiramisu. This exclusive collaboration between KARHU and zomer reimagines one of KARHU’s most comfortable running models, giving it a fresh coat and gentle zomer touch. The Mestari Run Kesä takes the KARHU running silhouette and reinterprets it through zomer’s bold, expressive lens.
The shoe is built around a performance-driven sole unit designed to provide balanced cushioning and dependable support. At the core is KARHU’s Fulcrum technology, guiding the foot through every step and creating a smooth rolling transition from heel to toe. The upper features a refined, almost ballerina-like silhouette that feels minimal and refined, finished with a subtle strap detail.
The KARHU Mestari Run Kesä blends technical performance with a streamlined, modern design. The perforated leather upper with binding creates a premium look while enhancing breathability and structure. Designed with a slip-on construction with elastic bands on the instep, the shoe offers a secure and comfortable fit. The half-length Fulcrum paired with a propulsion unit provide balanced support and forward momentum with every step. The AeroFoam+ midsole delivers lightweight cushioning while the rubber outsole provides dependable traction. Design element such as a reflective heel detail improves visibility in low-light conditions while adding a modern touch. A cushioned heel crash pad ensures smooth impact absorption and the open-cell PU insole enhances comfort and breathability. The Mestari Run Kesä comes with a special edition shoebox
