Had to return mine.  These are exceptionally comfortable on, however:  the manufacturer places diagonal slashes across the bottom of the soles to allow for easy flexing, for a seemingly comfortable walk.  Unfortunately if you have arch conditions or any extended walking in the forecast, this allows too much flex at midsole and fatigues the foot, much more so than in a normal shoe.  (come on Clark, shoe manufacturing 101)  Great looking shoe otherwise.

Clark needs to market these with a true quality sole for walking.  Would be a dynamite shoe then.
