Fair enough, I though it might be a certain style or something. Are running shoes that much more comfortable than say, a nice pair of "dressy" sneakers?
Seen as we're generalizing anyway, I think Japanese tourists tend to wear sneakers, but Chinese tourists do seem to wear running shoes. It's hard to say anything about Europe, because it's more diverse than the US, but I hardly see Europeans wearing actual running shoes as a part of their daily outfit, but they do wear a lot sneakers.
really? in what sense?
