Alexander McQueen Sneakers Size Chart: IT/EU, US and UK Conversion for the Oversized Sneaker

Catalog note: Album entries can change. Use the live album link and WhatsApp to confirm the current option before ordering.

Alexander McQueen labels its sneakers in IT/EU sizes, and the house's own size chart runs from IT/EU 38 to 49 in the men's table and 34 to 42 in the women's table, each with its own US, UK, Japanese and Korean columns. The only centimetre figure anywhere on that chart is the Japanese size column, which reads 25 cm at IT/EU 40 on the men's table and 27 cm at the same IT/EU 40 on the women's table; no insole length is published at all.

The shoe the search term is pointing at

“McQueen sneakers” almost always means one shoe in the house’s line-up: the Oversized Sneaker, a low-top in smooth calf leather on a deliberately oversized rubber sole. The house labels it in IT/EU sizes; the only centimetre column on its own chart is Japanese: 25 cm at IT/EU 40 on the men’s table, 27 cm at the same IT/EU 40 on the women’s. No insole length is published, and the label alone does not describe a pair’s length.

The brand’s own product data names five fixed features on it — round toe, McQueen signature, contrasting heel counter, oversized rubber sole, and an additional pair of shoelaces in the box — and adds, on the black colourway, “Perforated air holes, flat large laces and McQueen signature on tongue and heel. Leather lined.” Country of origin is listed as ITALY.

It is not the only shoe in the range, and the difference matters because the names are close. The official category data we pulled lists the Oversized Sneaker next to a Oversized Retro Sneaker, a Sprint Runner, a Tread Slick Lace Up, a Tread Slick Boot, a Flexion Sneaker, and — in media coverage rather than in the current category feed — a Larry sneaker and a Court Trainer. Tread Slick is the high-top on the same chunky sole idea; Sprint Runner and Flexion are lower running silhouettes; Oversized Retro is a separate body that shares the sizing system. When a listing says “McQueen trainers” or “McQueen sneakers”, the silhouette in the photos is the only reliable way to tell which of those you are looking at, because the size chart is common to all of them.

The men’s chart, from IT/EU 38 to 46 in centimetres

The chart below is the house’s own men’s table, taken from the size-guide content its product pages served, with the columns exactly as published: the label first, then the conversions. The Japanese column is the only one in centimetres and the Korean column is the same figure in millimetres (230 mm at the same label where the Japanese column reads 23 cm), which is why both are printed here.

Two things are worth reading off that table before anything else. The first is that the men’s chart starts at IT/EU 38 — there is no 36 or 37 in it, so a small-footed buyer is in the women’s table whether or not they intend to buy a women’s pair. The second is the step pattern: the Japanese column gains 0.5 cm for every half step on the label, so the gap between two adjacent half sizes is a half centimetre, not a full one.

The women’s chart, and the trap of two tables with one label

The house publishes a second table for women’s shoes, keyed to the same IT/EU labels but with its own conversions.

The women’s table carries an anomaly in its own last row: the US column runs 41.5 → 11.5 and then 42 → 9, which breaks the progression of every other row. We have printed it as published rather than correcting it, because a buyer comparing a listing against this chart should see what the chart actually says. The men’s table gives 42 → US 9 as well, so the two tables agree on that row and disagree on the pattern that leads into it.

Put the two tables side by side at the labels they share and the real trap appears:

The same printed label is two centimetres apart in the two official tables, at every shared step. UK numbers differ too — IT/EU 40 is UK 6 in the men’s table and UK 7 in the women’s table. The label on the tongue is therefore not enough to describe a pair’s actual length; the market the pair was cut for is the missing half of the sentence. This is also why “EU 40 = 25 cm” circulates as a fact: it is true of the men’s table and false of the women’s table.

What the centimetre column is, and what it is not

The Japanese size column is a market size expressed in centimetres, not a measured insole. That distinction decides how you should use it. An insole length is the measured length of the footbed inside the shoe; a Japanese size is a body measurement bracket the shoe is cut to. They are close, and they are not interchangeable — our regional shoe size conversion guide sets out how far apart the conventions run, and the Dior B30 size page is a worked example of the same gap on a different house’s chart.

Across every archived McQueen page we pulled, there is no insole figure at all — not in the size chart, not in the product details, not in the size selector. Three consequences follow:

• The chart cannot answer a length question on its own. Asking a seller for the insole length of the actual pair in centimetres is the step that turns the chart into something usable.
• Two generations of the chart disagree. An archived 2008 chart pairs US 5 with UK 4.5 and EU 38, while the 2020-era chart pairs IT/EU 38 with US 5 and UK 4. Half a UK size of drift between them, on the same label.
• Half sizes are real labels, not rounding. The chart steps in 0.5 from 38 upward, and the product pages we pulled list discrete half sizes (39.5, 40.5, 41.5) as individual options rather than as a range, so a half size is worth asking for by name.

”Fits true to size”, against advice to go a size down

The brand’s own product details carry one line on fit: “The style fits true to size.” Nothing about lasts, width, or what happens across a season. The outside advice around the shoe says something different.

Read together, the split is not noise. Everyone who says “true to size” is talking about the length; the “size down” advice is talking about the volume, and it comes from the width of the last rather than from the length. The two buyers at opposite ends of the width range describe exactly that: the narrow-footed one finds her usual size snug, the same size on a wide foot would push you up rather than down. If your feet are wide, the useful question is not whether the shoe runs big but whether the last is wider than what you normally wear.

There is a second, non-size fit complaint worth knowing before the pair arrives: the padded tongue starts stiff and long. One buyer’s account is blunt about it — “very stiff, sharp and long so it rubs and cuts into the ankle” — and adds that it settles with wear. That is a break-in detail, not a sizing one, so no size change fixes it; a slightly thicker sock for the first week does.

The sole figure everybody quotes, and the build around it

Exactly one number for the sole turned up in the sources: a resale platform describing “1.8-inch leather soles”, which converts to roughly 4.6 cm. Neither the brand nor the retailers we could reach publish a millimetre figure, so treat 4.6 cm as a single-source estimate and confirm it against the pair itself.

The rest of the build is documented and consistent:

• Upper: smooth calf leather on the core colourways, described in the product data as “white smooth calf leather” and “black smooth calf leather”; a graffiti-print version is listed as 100% calf leather, and a crystal-embellished version as 100% goatskin.
• Lining: “Leather lined” on the black colourway — the shoe is leather inside, not textile.
• Detailing: perforated air holes across the upper, large flat laces, and the McQueen signature in both places — tongue and heel.
• Heel counter: contrast is the point. Colourways in the feed pair a leather body with a heel counter in blue, blue-grey suede, zebra-print suede, or silver grey, and the house lists “Contrasting heel counter” as one of the shoe’s fixed features.
• In the box: an additional pair of laces, always; a dust bag, no longer — the product copy states the sneakers “come with an additional lace set” and that, to reduce cotton consumption, a dust bag is no longer provided with sneakers.

Product codes are the fastest way to tell two versions apart

Colourways share a silhouette and differ in the last three groups of the product code, and the heel counter is usually what changes. These are the codes we could confirm against official product data:

The pattern that matters when you are reading a listing: the first three groups of the code identify the shoe and the season, and only the last block changes with the colourway. Two listings that share the first ten characters are the same body, even when the heel counter is leather on one and suede on the other.

2014 or 2015, and the other debates worth skipping

The debut date is not settled, and it is worth knowing how unsettled before you repeat one. A retailer’s style guide dates the shoe to 2014 and calls it “a big fat three years before the Triple S”; a sneaker history site says 2015; a resale platform says the Spring/Summer 2015 season; and a fashion title says it was introduced for S/S 15 as a menswear style that was later run for women’s. Three of those four point at 2015 or its spring season, one says 2014, and no source reconciles them.

What is not disputed is the design read. A retail style guide describes the shoe as “part Stan Smith, part creeper” and credits its staying power to restraint — a “clean silhouette” that “features only the merest gesture of detailing with perforations punched into its upper and branding on the tongue”, which it calls one of the most wearable of the oversized sneaker offerings. A magazine profile adds the other half: oversized flat laces, an ultra-padded tongue, and a heel counter carrying the signature, all sitting on a billowing rubber sole.

The house context is stable and easier to check than the launch year. The size and silhouette sit inside a longer line that began with a footwear collaboration in 2005; Lee Alexander McQueen led the house from 1992 until 2010, Sarah Burton from 2010 until her departure announced in September 2023 after 26 years, and Seán McGirr from October 2023.

What to send before you commit to a pair

The size chart narrows the label; it does not settle the length. Four things resolve the rest, and all four can be sent in one message:

1. A tape across the insole, heel to toe, in centimetres. The brand publishes no insole figure, so this is the only number that describes your actual pair.
2. The label size, as printed. IT/EU 40 or IT/EU 40.5 — not “US 10”, because the US number on these pages has been published two different ways for the same label.
3. The product code from the box or the listing. Ten matching characters mean the same body; the last block tells you which heel counter you should expect.
4. Your usual size in the chart you normally buy from, plus the market — men’s or women’s. That single word is the difference between 25 cm and 27 cm at the same label.

Send those with a screenshot of the colourway you want and we will photograph the actual pair against a tape, confirm the sole thickness and the heel-counter finish, and check the label size that is available. Open the shoes catalog for what is currently in the album, or compare the fit approach on a Gucci Ace or a Golden Goose if you are still choosing between silhouettes. The McQueen rows sit with the other sneaker charts in the site’s Luxury Bag Size Index, each entry naming the guide it came from.
