I'm moving offices in a couple weeks and will be walking significantly more. My current work shoes are fine for walking short distances, but frankly suck for anything over a stretch of a tenth of a mile. I'm hoping that some of you might have some recommendations for good leather shoes that are comfortable to walk around in. I'm looking to spend something around $100-$200 a pair, but feel free to make recommendations outside that range. The shoes don't have to be super dressy, but should at least be able to go with khakis/slacks and a dress shirt.
