Are they appropriate footwear in a chinos/dress shirt combo or are they too casual, even for this relaxed business-casual outfit? If it makes any difference, it's not uncommon for my coworkers to wear jeans, tennis shoes, and a polo shirt, so casual isn't really an issue. I'm more interested in knowing if driving shoes can be pulled off with trousers. Also, if you had to choose, would you go with suede or leather? I've got 2 options I'm looking at and prefer the leather ones, but they're harder to come across.
