I started wearing Docker's shoes when they first came out (maybe mid-90's?) and they have come a long way. These shoes look great around the office (even with a suit). There is a gel-pack in the heel which is very comfortable. I have these in black and brown and they take a heck of a beating before I replace them.

Yes, you will have to forgo expensive features like leather sole and steel shank but for 50-75 bucks these can't be beat.
