Black FIVE TEN District clips have been the best casual cycling shoes I've ever used, but sadly they don't seem to make them anymore. I got my last pair unused on ebay. I wear them all day 5 days a week. My ATAC cleats last way longer too thanks to the deep cleat recess. Several people at traffic lights have been surprised to find out they're clipped.
Quoc Pham Hardcourt hi tops were my favourite for both looks and comfort, but after both pairs snapped within 3 months I had to admit defeat.
