Our balls are collected from partner tennis clubs in Porto, just a few kilometres from our workshops!
The balls (rubber and felt) are crushed into fine granules, then mixed with recycled rubber. This mixture is then hot-pressed in a mould to form the sole.
A tennis ball is only used for a few hours, but takes 400 years to decompose. In France, 14 million balls are thrown away every year due to a lack of recycling channels. So we decided to collect them and incorporate them directly into our trainers!
The collection is made in Portugal, in the Porto region, in order to stay as close as possible to the clubs where we collect the balls. Only the cap is made in France, in Montpellier, from upcycled fabric offcuts.
It is not strictly a limited edition, but we have chosen to produce an initial run in small quantities. Stock is therefore limited for this launch. If you like a style, we recommend not waiting too long!
