Roger Federer and Rafael Nadal faced off in The Clash of the Champions Tuesday night in Eugene at the new Matthew Knight Arena. Being that the event came together with a lot of help from Nike (each competitor is signed to the Swoosh), it should come as no surprise that there was some pretty flashy footwear on display. Roger Federer sported his usual Lunar Vapor 8 Tour, but more importantly (being that there’s a picture of it) are Rafael Nadal’s Nike Air Max Courtballistec 3.3—Matthew Knight Arena Edition. In addition to featuring Oregon colors, the shoe sports the Matthew Knight Arena logo on the tongue, the same logo present at halfcourt during basketball games. The shoes didn’t hurt Nadal’s game either; he beat Federer 7-5 in the exhibition match. Thanks to Mark Lawrence for the heads up.
