Tennis icon that changed the game in 1961. Launched in 1961 as a new innovation for professional on court tennis use. It has a signature three layer vulcanized outsole with elevated rubber protection, making the shoe extremely durable for tennis players on clay courts. For SS19 we have increased comfort and fit without changing the craftsmanship for the unique Tretorn three layers sole. We have also made it in 100% locally sourced canvas from Vietnam, and 30% natural, locally sourced rubber.
