Back in 2022, ON released a collaboration shoe between Roger Federer and Ronnie Fieg's KITH, in very limited quantities. The ON the Roger Pro x KITH (RF)² was sold in a package with the high top lifestyle shoe known as the Roger Clubhouse, priced at $550. Each shoe was all white, and interestingly included a bag of red clay to rub into the shoe.
Before landing on this final design Ronnie Fieg and Federer actually produced a few other sample pairs to consider for production. Ronnie Fieg highlighted the few samples on Instagram (https://www.instagram.com/p/ChscWknuf1q/?igshid=NTc4MTIwNjQ2YQ%3D%3D).
Special thanks to Prestige Memorabilia for images of the samples (you can buy them here)!
Many people actually expressed these unproduced sample designs were better, but let us know your thoughts in the comments!
