INTRODUCING THE MESTARI RUN KESÄ,
A NEW MODEL BY KARHU AND ZOMER

After the success of the first collaboration, KARHU and zomer come together once again for a second chapter. This time, the teams reimagine one of KARHU’s most comfortable running models, giving it a fresh coat and a gentle zomer touch. The Mestari Run Kesä takes the KARHU running silhouette and reinterprets it through zomer’s bold, expressive lens.

The idea was simple. Create something light, comfortable and joyful. A shoe made for everyday movement in the city. For people who are always on the go. Effortless, technical, but still elegant.



The design of the shoe begins with a performance-driven sole unit built to provide balanced cushioning and dependable support. At the center of the ride is KARHU’s fulcrum technology, which guides the foot through every step and creates a smooth rolling transition from heel to toe. On top, the shape feels almost like a ballerina shoe, refined and minimal, finished with a small strap detail.

Heritage in Motion

This collaboration is a dialogue between past and present—where KARHU’s legacy of Finnish craftsmanship meets zomer’s instinct for pushing boundaries. The Mestari Run Kesä reimagines a classic, proving that heritage is never static but always in motion.



Form Follows Play

zomer’s approach to design is rooted in curiosity and experimentation, while KARHU’s DNA is built on performance and precision. Together, they create something unexpected—where movement shapes the design and the shoe becomes an extension of the body.



Common Thread

More than a collaboration, this project is the result of a natural creative exchange. It’s about trust, friendship, and the shared belief that great design comes from instinct, spontaneity, and a willingness to see things differently.
