Messi and adidas have maintained an in-depth cooperative relationship for more than 15 years, covering professional match equipment, personal signature shoe lines and other core fields, while Kith, as a leading street fashion brand founded by Ronnie Fieg, has been committed to integrating niche culture, professional sports and daily fashion for many years, and has launched dozens of popular cross-border cooperative series with top global sports IPs. This joint project is the first time the three parties have carried out full-link cooperation from product design to cultural promotion, aiming to break the inherent boundary between professional football culture and public lifestyle. This collaborative series covers nearly 50 SKUs, including professional football match jerseys printed with Messi's personal No.10 logo and embroidered with World Cup championship commemorative patterns, retro-style leisure tracksuits, heavyweight cotton hoodies, functional windbreakers suitable for multiple scenarios, limited edition signature football boots that can be used for both professional competitions and daily wear, as well as peripheral products such as scarves, adjustable hats and custom mini footballs printed with the tripartite joint logo. Messi personally participated in the whole process of product design and style adjustment, and integrated many details of his career milestones, including the silhouette of the World Cup trophy, the time node of winning the 8th Ballon d'Or, and his own handwritten signature, into the hidden design of the products. Different from previous football-themed co-branded products that only focus on single professional or leisure attributes, this series perfectly combines the professional functional attributes of adidas Football products, Kith's consistent minimalist and advanced street aesthetic, and Messi's global iconic influence, breaking the stereotype that football culture is only limited to match scenes and fan gatherings. This cooperation has successfully extended football culture to the daily wear scene of the public, allowing consumers who do not pay attention to professional football matches to feel the unique charm of football culture through fashion products, greatly expanding the coverage and connotation of modern football culture. According to official data, the series was launched on Kith official website, adidas official mall and global designated offline stores on July 22, 2024, and 90% of the SKUs were sold out within 15 minutes of launch, and the related topics of the cooperation once rushed to the top 3 of global social media hot lists, triggering a rush to buy among football fans, street fashion lovers and collection enthusiasts around the world.
