Black
Any shoe color other than black is going to look too casual with a black suit. This is why most guys opt for charcoal gray or navy blue as an everyday-suit option. Moral of the story: Black suit, black shoes.

Blue Indigo
Bluer than navy, this lively hue is ideal for wear in the summer. Tan monk-strap shoes, oxblood brogues, and black braided loafers will all coordinate well with it. The less "business professional" the suit color, the more color options you will have for your feet.

Charcoal
Charcoal, like black, doesn't carry much in the way of color choice. You should never pair brown shoes with a charcoal suit: Dark browns look like you’re trying for a close match and coming up short, whereas light browns are too informal. Plain black works best; a deep burgundy (see the BOSS Black by Hugo Boss below) is a slightly more relaxed, elegant touch.

Gray
Stick with blacks and browns when wearing a gray suit. If you're wearing the suit with a white dress shirt and necktie, go for a classic black shoe. Matching your suits and shoes isn't a perfect science, of course; you should experiment with different brown tones to see which work best.

Khaki
Summertime brings with it a lighter palette. If you have a khaki suit hanging in your closet, be sure to pair it with pretty much any color but black — the severe color will awkwardly draw attention to your feet. Navys, burgundys, browns, and tans should do the trick.

Light Gray
A light gray suit looks great teamed with tan shoes. Standard black and browns will compliment it, but you have more versatility here and you should use it to show off your fashion prowess — because, yes, businessmen know how to dress.

Navy
For most guys, the navy suit is the workhorse of their weekday wardrobe. It's professional and the most flexible of colors: You can pair a navy suit with black, brown, or burgundy shoes depending on the
occasion. Black shoes are typical business dress, while brown are more relaxed — oxblood or burgundy offer the most playful, social vibe.

White
Suitsupply's white pinstripe suit has warm weather written all over it. For shoes, light browns leathers and suedes will coordinate perfectly — a muted gray Blucher is a great option as well.
