Mach & Mach Size Guide: Fit, Half Sizes and Comfort by Heel Height

Mach & Mach sizes in EU numbers, from EU 35 to 42 with half sizes on most styles, and most pairs, such as the Double Bow Leather Flats in Black, take your usual EU size. The exception is a small group of PVC pumps, including the Double Bow PVC Pumps 110mm in Silver, where the house advises half a size up. Below is the conversion table, the heel height of every line, and our comfort notes by height.

Mach & Mach sizing: EU, UK and US

EU is the native system, and every Mach & Mach product lists its sizes in EU. Use this table to convert. UK sizes are a straight step from EU, roughly EU minus 33. US women’s sizes are approximate, because American brands vary, so treat the US column as a guide rather than a rule.

Half sizes sit between these rows: an EU 37.5 falls between a UK 4 and a UK 5. If you already own Italian-made heels in an EU size that fits well, start from that number.

Does Mach & Mach run true to size?

For most of the catalogue, yes. The product notes for the large majority of styles give no advice to change size, so buy the EU size you wear in other European brands.

Three styles carry house advice to take half a size up, and all three are PVC pumps with an adjustable ankle strap:

• The Double Bow PVC Pumps 110mm in Silver, in PVC with mirror calf leather details.
• The Double Bow PVC Pumps 100mm in Silver, the lower version of the same shoe.
• The Diamond of Elizabeth PVC Pumps in Silver, a 110 mm pump with a hand-stitched pearl strap.

What “half a size up” means in practice: if you are an EU 38 in leather pumps, choose EU 38.5 in these. PVC has very little give compared with leather and satin, so a pump that feels snug on day one tends to stay snug. If you are already between sizes, take the larger of the two.

Mach & Mach size ranges: check each style

Most styles run the full EU 35 to 42 with half sizes, but not every one. A few examples from the Coveti edit:

• The Audrey Satin Flats in Blue run EU 35 to 41.
• The Double Heart Vintage Leather Combat Boots in Black and the Buckle Belt Vintage Leather Loafers in Brown run EU 35 to 41.
• The Diamond of Elizabeth Ring Toe Leather Mules in Gold run EU 35 to 40.
• The Crystal Net Black Mules with Straps run EU 36 to 40.

The size list on each product page is the one to trust.

Mach & Mach heel heights by style

Heel height matters as much as size when you are judging fit and comfort. These are the heights in the Coveti edit, measured in millimetres.

• 10 mm: every ballet flat, including Double Bow, Audrey, Lotus Flower and Crystal Net. See our Mach & Mach ballet flats guide.
• 30 to 50 mm: Buckle Belt loafers and the combat boots.
• 65 mm: Le Cadeau slingbacks such as the Le Cadeau Patent Slingbacks in Black, plus Double Bow kitten heels and some Galaxy and Crystal Button styles. More in our crystal kitten heels edit.
• 85 mm: Galaxy, Floating Pearl and Puffy Heart styles, such as the Galaxy Tulle Slingbacks in Nude and the Floating Pearl Satin Sandals Black and White.
• 95 mm: Crystal Flame, Sirene and Orchid, such as the Crystal Flame Red Round Toe Mules.
• 100 to 110 mm: the full Double Bow pumps, such as the Double Bow Satin Pumps in Pink. Our Double Bow heels guide lists every height.

Are Mach & Mach shoes comfortable?

It depends on the height you choose, more than the brand. Most Mach & Mach styles are made in Italy with leather linings, and many of the higher heels have an adjustable ankle strap that holds the foot in place. Those two details help. But a 110 mm pump is a high heel, and no lining changes that.

Flats and low heels, 10 to 50 mm

Wear them all day. Strapped flats such as Audrey stay on better than slip-ons, and nappa leather softens with wear. If a flat feels loose at the heel, the strapped versions solve it.

Kitten heels, 55 to 65 mm

The best balance for weddings, lunches and long evenings. A slingback strap adjusts as feet swell through the day.

Mid heels, 85 to 95 mm

Comfortable for a dinner and a few hours of standing. Mules at this height are easier than you would expect, because there is no back to rub, though you will walk a little more carefully.

High heels, 100 to 110 mm

Save them for sit-down events. Break them in at home on carpet for a few evenings first, and carry a flat. For a wider view of comfort across crystal brands, Coveti’s piece on whether Amina Muaddi shoes are comfortable covers similar ground, and the Amina Muaddi heel heights guide is a useful comparison.

Mach & Mach sizing around the world

United States

US women’s sizes run roughly two to two and a half above UK, so convert from EU with the table above. If you are a US 8, start at EU 38 and read each product’s fit note.

United Kingdom

Take EU minus 33 as your rule of thumb: a UK 5 is an EU 38. For Royal Ascot and summer weddings, a 65 mm heel is the sensible height.

The Gulf (UAE, Saudi Arabia, Kuwait, Qatar)

Go by the EU size inside your best-fitting European heels, and use the table above if you usually shop in UK and US sizes. Long wedding nights and Eid evenings favour mules and slingbacks, which are forgiving on fit.

Europe

EU is the native system. Compare with your other Italian-made shoes, and see Coveti’s Alexander McQueen shoe size guide and Amina Muaddi sizing guide if you already own those brands.

Mach & Mach size guide: common questions

Do Mach & Mach shoes run small?

Most Mach & Mach shoes run true to size in EU. The house advises half a size up in three PVC pumps: the Double Bow PVC Pumps in Silver at 100 mm and 110 mm, and the Diamond of Elizabeth PVC Pumps in Silver.

What sizes does Mach & Mach make?

Mach & Mach makes most styles in EU 35 to 42, with half sizes on most of them. Some styles stop at EU 40 and EU 41, so check each product’s size list.

What is an EU 38 in UK and US sizes?

An EU 38 in Mach & Mach is a UK 5 and roughly a US 7.5 to 8. US sizes are approximate.

Should I size up in Mach & Mach heels?

Only where the house says so. Mach & Mach advises half a size up in its Double Bow PVC Pumps in Silver and Diamond of Elizabeth PVC Pumps in Silver; for most other styles, take your usual EU size.

Are Mach & Mach heels comfortable?

Mach & Mach heels have leather linings, and many high styles have an adjustable ankle strap, which helps. Comfort depends mainly on height: the 65 mm styles are easy to wear for hours, while 110 mm pumps suit sit-down evenings.

What is the lowest Mach & Mach heel?

Mach & Mach ballet flats sit on a 10 mm heel. The lowest heeled pumps in the Coveti edit are the 65 mm Le Cadeau slingbacks and Double Bow kitten heels.
