OT: most comfortable -office- shoe?

Variations on a Theme of XXtwindad

Piggybacking on the momentum of the other thread:

Early last year I got a painful and lingering case of plantar fasciitis, and after lengthy experimentation ended on some $40 Skechers foamycloud things. It was instant relief, and I've had no pain since. I'm also comfortable in my Birkenstock and Chacos sandals.

But, they look a little goofy in the office. I still wear them though.

I don't need fancy dress shoes at work, but semipro/simple would be good.

Your basic black shoe that works well with modern business casual, whatever that is...

Thanks.
