We focused on the durability of KD900X. They have been tested for 1000km mileage by runners, and even up to 1500km by one of them! Numerous studies have also shown that a lighter shoe improves racing performance through better energy conservation. Therefore when designing KD900X, we chose lighter components and worked on an optimized sole design.
To achieve such a feat, we worked closely with both internal and external partners. We developed our own carbon plate, and the Pebax® VFOAM foam with external partner Arkema, a renowned company leading in the development of innovative materials.
