Men's Monk Strap Shoes: Single vs Double, and How to Wear Them

Updated August 2026

A monk strap is a closed dress shoe fastened with one or two buckles instead of laces. It sits between an oxford and a derby on formality: cleaner than a derby because the vamp is closed, less severe than a cap-toe oxford because the buckle draws the eye. A single monk is the quieter one; a double monk is the recognisable one.

The style takes its name from the closed, buckled shoes worn by European monks, and it survived into modern tailoring for a practical reason: a buckle adjusts across the instep in one movement. That makes a monk strap the easiest dress shoe to put on, and the most forgiving one for a high instep — the same problem a derby solves with open lacing, solved with hardware instead.

This guide covers what separates single from double, how formal each one is, what to wear them with, how they should fit, and what changes as the price goes up.

What Is a Monk Strap Shoe?

A monk strap has no laces: the vamp is closed by a leather strap that crosses the instep and fastens with a metal buckle. Everything else — the last, the toe shape, the welt, the sole — follows the same rules as any other dress shoe.

Two details decide how the shoe reads:

• The number of straps. One strap is the more formal arrangement. Two straps stacked across the instep make a wider, more decorative panel.
• The hardware. A small, matte or antiqued buckle keeps the shoe quiet. A large, bright buckle turns it into the loudest shoe in the room.

Monk straps are made in every construction, from cemented to Goodyear welted. The construction does not change the formality, but it changes how long the shoe lasts and whether it can be resoled.

Single Monk or Double Monk — What Is the Difference?

A single monk has one strap and reads as a business shoe. A double monk has two and reads as a style choice. Both are correct dress shoes; they simply speak at different volumes.

Buy the single monk first if the shoe has to hold up in a conservative office or beside a suit. Buy the double monk first if you already own a black oxford and a brown derby, and want a third pair that is recognisable rather than safe.

Cobbler Union builds both in Almansa, Spain, Goodyear welted by our artisans, one pair at a time: the Chris single monk and the Francis double monk, each $490, with museum calf versions of the Francis at $540 and a lightweight version at $515.

How Formal Are Monk Strap Shoes?

A monk strap is appropriate for business, for most weddings and for any office short of a formal dress code — but it is not a black-tie shoe. For black tie, wear a plain black oxford or an opera pump. Everywhere below that, the buckle is not a problem.

Our wedding shoe guide sets out the shoe by dress code if the invitation is specific.

What Do You Wear Monk Straps With?

A monk strap works with anything a derby works with, plus most things an oxford works with. The rule is the same as for any dress shoe: the shoe should be at least as formal as the trousers.

• With a suit — a single monk in black or dark brown, plain toe, slim last. Works with flannel, wool and navy. For charcoal and formal evening suits, an oxford is still the better shoe.
• With odd jackets and trousers — a double monk in dark brown or cognac. This is the pairing the style was revived for, and it holds up in almost any office.
• With chinos — either, in mid brown, tobacco or cognac. Break the trouser cleanly on the shoe so the buckle stays visible.
• With denim — a double monk in brown or oxblood, ideally on a rounder last with a slim rubber sole. Avoid black with blue denim; the contrast is harsh.

Belt rule: match the belt leather to the shoe, and keep the belt buckle in the same metal family as the shoe buckle. It is the one detail people notice on a monk strap and nowhere else.

Should Your First Monk Strap Be Black or Brown?

Buy dark brown first, unless the shoe has to work with a black suit or a formal dress code. Black monk straps are correct and useful, but a black shoe with a buckle competes with the plain black oxford most men already own. Dark brown covers the ground where a monk strap has no competition: business casual, odd trousers, chinos, denim.

• Dark brown — the most versatile. Works from a navy suit down to jeans.
• Black — for formal business, interviews and anything approaching a strict dress code.
• Cognac and tobacco — spring and summer, odd jackets, lighter tailoring.
• Oxblood — the one that reads as a decision rather than a default, and the best partner for grey and navy.

How Should a Monk Strap Fit?

Size the shoe to the widest part of your foot, then use the strap to close the instep — never the other way round. The buckle adjusts one dimension only. If the shoe is too wide in the forefoot, the strap will not rescue it.

• High instep — a monk strap is one of the two best dress shoes for you, alongside a derby. Let the strap sit at the second or third hole rather than pulled tight to the last one.
• Wide forefoot — the last matters more than the closure. A fuller last in the correct width beats going up a size in a narrow one.
• Heel slip — check it with the strap fastened. A little movement on a new welted shoe settles as the insole moulds; a lot means the last is wrong for your heel.
• Double monks — fasten both straps. Leaving the top one open is a photograph trick, not a way to wear the shoe.

Our guide to lasts and fit explains how last shape changes fit at the same nominal size.

What Separates a Well-Made Monk Strap From a Cheap One?

Three things, in this order: the leather, the construction, and the finishing. None of them are visible in a product photograph, which is why price alone is a poor guide.

The leather. Full-grain calfskin keeps the outer surface of the hide intact — the densest, strongest layer, the one that takes cream and wax and develops a patina. Cheaper shoes use corrected grain: the surface sanded to remove scars, embossed with a printed grain, sealed under pigment. It looks even on the shelf and stays that way, because the layer that would age has been sanded off. Every Cobbler Union upper is full-grain European calfskin, and on several models we can name the house — the black calf on the Francis comes from Weinheimer in Germany.

The construction. A Goodyear welt stitches the upper and welt to a leather insole, so the outsole can be replaced without touching the upper. The alternative at the low end is cementing — the sole glued on, the shoe finished when the sole wears. Both Cobbler Union monk straps are Goodyear welted.

The finishing. Leather lining rather than fabric, a leather insole that moulds to the foot, a firm heel counter that holds shape, hand-burnished colour with depth rather than flat pigment, and a sole edge finished cleanly. This is where bench time goes, and it is what separates two shoes with the same specification sheet.

How Much Should a Monk Strap Cost?

A Goodyear welted monk strap in full-grain calfskin starts around $300 and runs past $900 at the traditional English and American houses. The interesting band is $400–500, where artisanal construction sold direct becomes possible.

Cobbler Union sells direct from the workshop, with duties included and returns handled from the US, which is the whole explanation of the number: the construction and materials belong to a $900 shoe; the price reflects the business model.

Frequently Asked Questions

Are monk strap shoes formal enough for business?

Yes. A single monk strap in black or dark brown calfskin is appropriate for almost any business setting, including interviews. It is less formal than a plain cap-toe oxford and more formal than a derby. For strict black tie, wear a plain black oxford instead.

What is the difference between a single monk and a double monk?

A single monk has one strap crossing the instep and reads as a discreet business shoe. A double monk has two stacked straps, a wider decorative panel, and reads as a deliberate style choice. Both are correct dress shoes; the single is the safer first pair.

Can you wear monk straps to a wedding?

Yes, for everything below strict black tie. A black single monk works for a formal wedding, and a dark brown or oxblood double monk works for daytime and semi-formal weddings. For black tie, wear an oxford or an opera pump.

Should you buckle both straps on a double monk?

Yes. Fasten both straps so the panel sits flat across the instep. Leaving the top strap undone is a styling trick from photography, and in person it reads as a shoe that does not fit.

Are monk straps good for wide feet or a high instep?

Yes, particularly for a high instep. The strap adjusts across the top of the foot in the same way open lacing does on a derby, so it accommodates height that a closed-laced oxford cannot. For a wide forefoot, the last still matters more than the closure.

Black or brown monk straps — which should I buy first?

Dark brown, unless the shoe has to work with a black suit or a formal dress code. A black monk strap competes with the black oxford most men already own, while dark brown covers business casual, odd trousers, chinos and denim, where a monk strap has no real competition.

Can you wear monk straps with jeans?

Yes. A double monk in brown, tobacco or oxblood is one of the best dress shoes to wear with denim, ideally on a rounder last. Keep black monk straps for tailoring — with blue denim the contrast is harsh.

How is a monk strap different from an oxford or a derby?

An oxford has closed lacing and is the most formal of the three; a derby has open lacing and is the roomiest; a monk strap has no lacing at all and sits between them. Our guide to oxford versus derby shoes covers the two laced constructions in detail.

How much should a well-made monk strap cost?

A Goodyear welted monk strap in full-grain calfskin starts around $300 and runs past $900 at the traditional houses. Cobbler Union monk straps are $490, in full-grain European calfskin, Goodyear welted by our artisans in Almansa, Spain, sold direct with duties included.
