If you run into Roger Federer on your way to board a plane, do not be surprised if he looks you up and down, or mostly down. That’s because Mr. Federer has something of a sneaker fixation.
The Swiss tennis champion is not an “obsessive,” he said (slightly hard to believe about someone who has won 20 Grand Slam trophies), but still he is “always looking at other people’s feet in airports.”
Earlier this month, when Mr. Federer was in London to play in the ATP Finals, he said in an interview that he owns at least 250 pairs of sneakers.
