The adidas Pharrell x Tennis Hu 'Scarlet Red' is a collaboration between superstar producer Pharrell Williams and adidas. According to Williams, the "Hu" in the name stands for "health ultimatum," as his goal with this collaboration is to celebrate the shared experiences and connections of humanity through the use of vibrant color. In this version, the iconic slip-on mesh tennis silhouette is fully dipped in a bold red hue, extending to both the midsole and a significant portion of the outsole. The branding features a red trefoil symbol on the white tongue patch, while white accents on the outsole provide a contrasting touch.
