I recently changed jobs and I'm now in an industry that, while I'm in a very white collar position I'm sometimes required to visit blue collar work sites (mainly mining coarse refinement plants).  These boots are ideal because they don't scream "work boot" and aren't out of place with dark slacks or even a suit (given the conditions).  They have also become bad-weather shoes, again even with slacks or a full suit, especially when traveling into Canada, New England, or the northern Midwest.  They won't quite be at home in a board room in a non "heavy-duty" industry, but if you have to mix white and blue collar, these are a great boot.

Fit is true to size both in length and standard width.  Arch support is not overly pronounced but comfortable for my average arch.  The gusset makes break-in far less painful than lace or zip up boots.  The only issue so far has been that the leather below the pull-tab is a bit stiff and can rub the back of your leg if you move from sitting to standing and back frequently.  Over about a week of continuous wear it has began to soften a bit, but may take a bit more continuous wear before I would consider it "broken in".  This is also somewhat the nature of a slip on Chelsea-style boot, since the top opening can't form fit to your leg and still slip on/off easily (even with the gusset).
