I kind of figured these would be fine for casual wear, but I wind up wearing them for hours on end.  They're good in the arch and great on grip and lateral support.  I'm a pretty big guy, and having that level of support is something I appreciate.  I have the black ones, and it's a nice even coloring throughout.  The shoes actually come with white laces in the shoes and black laces included.  They're lightweight and reasonably breathable.

The width is average.  I find Nikes a little narrow and Rockports a little wide.  I hope this helps.
