Real Madrid star Kylian Mbappé was spotted at Valdebebas testing out the first-ever football boots produced by Swiss sportswear brand On. The French forward wore prototype pairs during a recent training session, signaling a major expansion for the brand beyond running and lifestyle footwear into elite performance football.
The whiteout prototype boots feature On’s signature CloudTec cushioning technology adapted specifically for on-pitch traction and acceleration. The design incorporates a streamlined silhouette with a textured upper for enhanced ball touch, paired with a custom stud plate layout developed for high-speed multi-directional movement.


The appearance follows months of industry speculation surrounding Mbappé’s footwear partnership, as his long-standing agreement with Nike approached its expiration.
The World Cup champion becomes the main spokesperson for the brand’s recently established On Football division after his transfer to On was announced.
Mbappé will actively participate in the development process, collaborating closely with product design teams to test and improve upcoming clothing and footwear versions. On’s formal foray into football performance gear is highlighted by the on-field debut, which brings athlete-led insights straight to the field.
