Tested and approved in use for tennis and school sports activities by very active children!!! Particularly lightweight, they are also sturdy and can stand up to the wear and tear children might inflict on them daily, during any physical activity and on any type of surface. The thick soles absorb impacts well. Sports halls won't get the better of them!
Before being used on the tennis courts, our shoes are put through several tests: in the laboratory and on the court. Lab tests are carried out to validate the following components: tearing eyelets and straps, gluing, toxicology, UV resistance, abrasion resistance of outsole and upper components, accelerated ageing. The field tests serve to approve our products on a tennis court in real playing conditions.
