I have the blue/white pair, and I find them comfortable enough for pretty much everything I do (but I don't work on my feet all day.)  I like the elastic shoelaces, although unfortunately, once they get dirty they tend to stay that way unless you spot clean them. Another thing I dislike is that there's a lot of exposed stitching, eventually the shoes start looking kinda raggedy. However, they are the perfect shade of blue to me.
