The sport of track and field is close to Karhu’s heart. Across the decades, Karhu has appeared on podiums at the Olympics, national championships and at collegiate championships. At its core, track and field’s various disciplines serve as the basis of all sports, which is why it is also known as “athletics”.
Karhu’s latest release of its Performance running shoes draws inspiration from the sport we admire most the “Track & Field” pack. “In the 60s and 70s, when I was training and racing in Finland,” says Karhu Chairman, Franco Arese, “I learned the tracks had a unique color compared to other countries, they were black! However, these tracks were really good for racing."
