I bought these shoes for a 2-week trip with lots of walking. They held up well with only a few days of break-in required to make the insole conform to my foot. I bought the all-black pair. They are light, and very breathable. So breathable that I could feel the wind on my toes. The only down side is that I built up a lot of static electricity when walking on marble. Maybe it's the shoe, maybe it's the way I walk, not sure. But my wife found it annoying that she would get shocked every time she touched me while walking around (turns out Italy has a lot of marble flooring). I've worn similar nike shoes for the past few years and never had a static electricity issue before.
