Back in 1977, the Karhu Mestari made its debut and stayed as a fixed value until 1984. Forty years later, Karhu brought back the international hit that sold over 1.000.000 pairs globally. When it first launched, the Mestari was known for the patented Karhu air cushion midsole and the colourful design caught the attention of competitive runners.
