You read that right - I run marathons in these. I bike to work in them, and I wear them in board meetings. Finally - a running shoe that's work-place appropriate.

Especially useful when I have to go a mile or more from my office to get lunch - instead of taking my bike or car from the office I just run there (couldn't do that in regular dress shoes without risking injury)

I have one plain pair in black, and one wingtip pair in brown. The brown wingtip looks especially good with khaki's and an un-tucked shirt. The black ones are good for business casual, but I've worn them with a very formal suit before and stil pulled it off.
