Buy one pair of black cap-toe oxfords and stop shopping

The one

A black cap-toe oxford in smooth calf leather, with a stitched-on sole. Buy that and you're done.

The spec profile:

• Style: closed-lacing oxford, meaning the lace panel is sewn under the front of the shoe. One straight seam across the toe cap. No extra perforations or decoration.
• Color: black. Smooth leather, not patent, not suede.
• Toe shape: softly rounded. Not pointed, not chiseled, not squared off.
• Construction: the sole is stitched on (a Goodyear welt is the best-known version), not just glued. The maker should say so on the product page. If it says nothing, assume glue.
• Sole: thin leather, or leather with a rubber half-sole if you live somewhere with real winters.
• Lining: leather, so the inside breathes and holds its shape.
• Size: whatever passes the fit checks below, which matters more than anything else on this list.

Why this one

You'll get a call on a Wednesday night. The funeral is Friday morning, and the dress code is "dark suit."

That's the day this pair is for. Everybody owns shoes for the easy occasions. The one pair you can't be caught without has to work on the hardest, shortest-notice day, and black cap-toe oxfords are the most formal thing a normal man needs. They go with a navy suit, a charcoal suit and a black suit. They work at a wedding, at an interview and in a courtroom. Our guide on what to wear to a wedding, a funeral and an interview leans on this shoe for a reason.

Brown is friendlier. Black is safer. When you own one pair, safe wins.

Stitched construction is the money decision. A glued sole is done when it wears through. A stitched sole can come off and be replaced by a cobbler. Take a worked example, labeled as one: say the shoes cost $300 (an example, not a quote) and a resole costs a third of that. You've bought a second life for a fraction of a second pair. Some makers also run their own recrafting programs, so check whether the brand you're considering does and read the terms.

Leather matters next. "Genuine leather" on a label tells you very little. It's a grade, not a promise. Look for full-grain calf and a leather lining, and expect the product page to say so plainly. If it's vague, the shoe probably is too.

Brand comes last. A well-fitted shoe from a modest maker beats an ill-fitting one with a famous name on the insole. The same rule runs through the checks that tell you a garment actually fits, and it's harder to ignore with shoes, because a bad fit blisters you at the worst possible time.

The fit test

Shop in the afternoon, when your feet have swelled a bit. Wear the socks you'll actually wear with a suit, which are thin. Then check:

• Your longest toe should sit roughly a thumb's width from the end.
• The ball of your foot should land in the widest part of the shoe.
• Your heel can slip a little in a new leather shoe. It shouldn't pop out with every step.
• Walk around the store for ten minutes. If anything pinches now, it will pinch at the reception.

Try both feet. One is almost always bigger, and you fit the bigger one.

Make it last

Buy a pair of cedar shoe trees. They cost little and soak up moisture and hold the shape. Give the shoes a day off between wears. Polish them every few wears with a cream and a wax in the matching color. A man whose shoes are clean and cared for looks like he has his life together, and that happens to be a decent way to live.

What to skip

Pointed toes. They date a shoe quickly and punish your feet.

Patent leather. That's tuxedo territory, and it cracks.

Anything labeled only "genuine leather" with no detail. Ask the store what the upper is made of. If nobody knows, walk.

Memory foam and gel insole claims. A dress shoe is built to be sleek, and padding is a sneaker's job. If your arches need support, a separate insole does it better.

Buckles, chains, contrast stitching and logos. Every one of them dates the shoe or takes it out of the formal column.

A second cheap pair "just in case." Put that money toward the one good pair.

Fancy add-ons at the register. Protective sprays and leather treatments are optional. Shoe trees and a basic polish kit aren't.

If your situation is different

You wear brown, olive or tan a lot. Go dark brown instead. It pairs better with those colors. You'll feel the limit the day you need to wear a black suit, so choose with that in mind. If your wardrobe leans casual, what smart casual actually means will tell you whether a derby or a loafer fits your week better.

You're on your feet all day, or your winters are wet and icy. Choose a thin rubber sole, usually sold under a studded or lugged name. It grips better in rain and snow, and the trade-off is a slightly less formal look. For a man in Minnesota in January, that's the right trade.

You have wide or narrow feet. Look for makers that sell half sizes and multiple widths. Don't squeeze into a standard width because it's what the store had. Ask what they can order.

You can't spend much right now. A glued-sole shoe that fits beats a stitched shoe that doesn't. Buy the best-fitting pair you can afford, use shoe trees, and replace them when they're done. Just don't pretend a $60 shoe can be resoled and then wonder why the cobbler winces.

Before you buy

• Try them on in the afternoon, with dress socks, on both feet.
• Confirm the leather type and the sole construction from the maker's own description.
• Ask whether the sole can be replaced, and whether the maker offers resoling.
• Read the actual warranty document: how long it runs, what it excludes, what voids it, and who pays shipping.
• Read the one-year-later owner reviews and look for complaints about the soles or the lining.
• Check the return policy for shoes you've walked on indoors.
• Check the current price.
