Tests are carried out at our TechCenter by our product engineers. We also carry out toxicology tests. Lastly, our shoes are tested on badminton and squash courts by panels of players.
For hygiene reasons we recommend storing your shoes in a cool, dry place and removing the insoles after use to air them out.
