Tinker Hatfield designed the Vapor 9 Tour on his iPad while sitting with Roger Federer, ushering in a whole new era of design. And unlike many first attempts, the Vapor 9 Tour was perfect right out of the box. Possibly the best Nike Tennis sneaker since the glory days of the Tech Challenge, the Vapor 9 Tour is best appreciated in mesh toebox form, graced in the official Wimbledon purple and green. A future classic.
