Playing in today’s US Open final match, Swiss born Roger Federer is heralded by many as the best tennis player in the world. Nike, a long time Federer endorser, will be holding a product installation featuring the new Federer line alongside +41 and special guest DJ AM. Along with free drinks, ice cream and access to the Nike i.D. booth, it will surely be a great event. The in-store reception will begin at 5pm at the 0808 Nike Sportswear Store in Berlin, September 9th, 2008.
