A while back I had seen these in stores and thought at the time the slogan was silly and walked on by.  I wanted something for airline travel as my work needs have changed and these kick tail.  Extremely comfortable, look cool with jeans, shorts or casual slacks, easy on and off through security and really comfortable (I meant to write it twice).
I was a little nervous about sizing after seeing reviews stating the shoes are both under and oversized so here's my two cents worth.  Nikes run small, I usually wear a twelve; Avia, Reebok and Adidas I normally wear elevens; boots usually a ten and a half wide or eleven regular.  I took a shot on elevens and they worked out very nicely.  A little snug if you are wearing thick athletic socks but still comfortable, so if you are a thick sock kinda guy I would go up a half size.  Cheaper athletic or thinner styles of socks the elevens are quite comfy.
