Do the Newtons run small? Do you normally have size 10 shoes run small? I wear a 9.5 in the Asics Kayano and have been looking into agetting a pair of Newtons? Not sure that I should jump up to a size 10 though.

I think that they run fairly true to size. I actually wear an 11 in the DS Trainer, 10.5 in the Zoot Ultra Race if that helps. I dont know what I was thinking going down to a 10 because they definitely a bit small on me. It was an impulse buy.
