Dior Size Chart India: B22, B23, and B30 Sneaker Fit Guide
Dior sneakers are sized the European way, and Dior's own numbering does not line up with the EU size printed on a Nike or Adidas box the way you would expect. A Dior 42 and a generic EU 42 are close but not identical, and the B22, B23, and B30 each fit a little differently on top of that. This guide gives you Dior's own size conversion, plus the specific fit notes each silhouette needs before you commit to a size on a five figure purchase.

Two things make Dior sizing trickier than most luxury sneaker brands. First, Dior publishes its own size scale (labelled simply "Dior" on the official size chart) that sits a step apart from generic EU, UK, and US numbers, so cross checking against a size you already own in another brand can mislead you. Second, the B line sneakers do not all fit the same. The B22 leans snug through the midfoot, the B23 narrows through the vamp, and the B30 sits closer to a standard sneaker last. The chart below gets you to the right number; the notes after it tell you which way to lean.

The one rule that fixes most Dior sizing mistakes
Do not size Dior off a sneaker you already own from a different house. Dior's own scale runs a touch smaller through the toe box than a typical Nike or New Balance EU size, which is exactly why buyers who go "true to my usual EU size" sometimes end up half a size tight. Measure your foot length in centimetres using the table above as the anchor, then apply the model specific note below, not the other way around.
Indian frame translation
Most Indian buyers land between Dior/EU 41 and Dior/EU 44 on the men's chart, and Dior/EU 37 and Dior/EU 40 on the women's chart. If your foot measures right on the line between two rows, the model specific advice below decides which way to go, since Dior does not sell every size in every colourway anyway; availability is often limited to a narrow band of UK sizes per pair.
India commonly retails shoes using the UK numbering already shown in both tables above, so the UK column doubles as your India size reference. If a shoe you already own is labelled "UK 8" in India, start your Dior search at Dior/EU 42 on the men's chart and adjust from there using foot length, not the label alone.
B22, B23, B30: silhouette fit notes
Dior B22 (the everyday trainer)
The Dior B22 is the house's most worn sneaker, and the model most buyers oversize on. Buying guides and long term wearers describe the B22 as running snug rather than roomy, particularly through the midfoot; the common advice is to take your true to size measurement, and go half a size up only if you have a wider than average foot. Narrow to medium feet should stay on the chart number, not size up preemptively.
Dior B23 (the high top canvas)
The B23's Dior Oblique canvas upper narrows noticeably through the vamp compared to the B22's smoother leather panel. General guidance across Dior shoe reviews notes the house's dressier styles running small through the front of the foot, and the B23 inherits some of that. If your foot measurement sits between two sizes, take the larger one on the B23, especially if you plan to wear it with socks rather than barefoot.
Dior B30 (the retro runner)
The Dior B30 sits closer to a standard chunky trainer last, with more room through the toe box than either the B22 or B23. Most wearers find the chart size accurate here without adjustment. If you already know you size up on the B22, treat that as your starting point for the B30 too, then confirm against the foot length column.
When Dior's chart and the shoe's actual fit disagree
Limited edition and collaboration colourways on the B22 and B23 sometimes ship in a narrower size run than the mainline shoe, since Dior produces smaller batches for these drops. If you are eyeing a specific pair like the Dior B22 White Black Green Gold or the Dior B23 Low Top Black Cd Diamond, check the exact size list on the product page before assuming your usual number is in stock; Dior sneakers are often listed in a narrow band of two or three sizes at a time rather than the full run shown in the chart above.
Every pair listed on Kicks Machine goes through an in house authentication check before it ships, including a size stamp and box tag match, which matters more on Dior than on most brands since counterfeit box swaps in the luxury sneaker resale market are common enough to catch a size label that does not match the shoe inside.
Care tip: a well fitting pair protects the investment
A Dior sneaker that runs even half a size loose lets your heel slide inside the counter with every step, which stretches the leather or canvas panel out of shape faster than normal wear would. A pair that is too tight creases across the widest part of the toe box within weeks. Getting the size right the first time is the cheapest way to protect a shoe in this price range; our sneaker care collection stocks the brushes and cleaners suited to the leather, canvas, and technical fabric panels Dior uses across the B line.
Frequently Asked Questions
Does Dior run true to size?
It depends on the model. The B30 runs close to true to size on the chart above. The B22 runs snug through the midfoot, so wider feet often need half a size up. The B23 narrows through the vamp and can need the same half size adjustment. Measure your foot length first, then apply the model note.Is the Dior B22 tight on wide feet?
Yes, more than average. The B22's midfoot panel sits closer to the foot than a typical sneaker, and wearers with wider feet commonly go half a size up from their measured Dior size. Narrow to medium feet usually stay on the chart number. Check the exact sizes in stock on the [Dior B22 White Black Green Gold](https://www.kicksmachine.com/products/dior-b22-white-black-green-gold-sale) before deciding.Does the Dior B23 run narrow?
Yes, through the front of the foot. The Dior Oblique canvas upper narrows more than the B22's leather panel, and buyers between two sizes are usually better off taking the larger one, especially if wearing socks. The [Dior B23 Low Top Black Cd Diamond](https://www.kicksmachine.com/products/dior-b23-low-top-black-cd-diamond-sale) is a good reference pair to check against your own measurement.Is Dior sizing the same as UK sizing in India?
Not exactly, but close. Dior publishes its own numbering scale alongside EU, UK, and US equivalents, and India retail commonly uses the UK number as the reference size. Use the UK column in the charts above as your India starting point, then confirm with foot length in centimetres, since Dior's own scale sits slightly smaller through the toe than a generic EU size from another brand.Does Dior make half sizes?
Yes, across most of the B line, including the B22, B23, and B30, in half size increments as shown in the charts above. Stock availability per colourway is often limited to a narrow band of sizes rather than the full run, so always check the live size list on the product page before assuming your size is in stock.Why do Dior sneaker box tags matter for sizing?
Because a mismatched box tag is one of the more common signs of a swapped or counterfeit pair in the resale luxury sneaker market, and a wrong tag often means a wrong actual size inside the shoe as well. Kicks Machine checks the size stamp against the box tag on every Dior pair as part of its in house authentication process before dispatch.Closing thoughts
Dior sizing comes down to two decisions: which number on the chart matches your measured foot length, and which way the specific model pulls from there. The B22 leans snug, the B23 narrows through the vamp, the B30 sits closest to true to size.
