Building on the performance of the legendary Ubersonic models, the adizero Ubersonic 4 offers three new innovations that together guarantee an unprecedented experience The Lightstrike midsole provides super light cushioning for fast movements without sacrificing feel. The woven PRIMEGREEN mesh upper offers stability, supports lateral movement and directional changes and is layered on a comfortable, breathable knitted stocking construction. The model is available with both hard court and sand court soles.
In addition to improving performance, the collection was developed with adidas' commitment to eliminating plastic waste in mind. The face fabric is made of PRIMEGREEN - a high-performance yarn made from 50% recycled material, which contributes its share to the brand achieving a total volume of more than 50% recycled polyester by the end of 2020 and using only recycled polyester in all products throughout the company by 2024.

The adizero Ubersonic 4 is launched in a limited "Top Secret" colour scheme, which is based on the bold imprints known from legendary sports cars. The sharp, angular lines in the design are the expression of a visual language that emphasizes speed and faster playing.
