Christian Louboutin Sizing: How Every Major Style Fits (UK Guide)

Quick Answer: Christian Louboutin Sizing

Last updated: March 2026

Most Christian Louboutin styles run narrow, and many people find they need to size up half a size, particularly in pointed-toe pumps. The degree varies by model: the So Kate is the most demanding on width, while styles like the Simple Pump are considerably more forgiving. If you are buying pre-owned and cannot try the pair on first, knowing your EU size and the specific model's fit profile is essential.

- So Kate and Pigalle: Narrow last; most people size up half a size

- Kate family (70/85/100): Rounder toe box; more accessible for a wider range of feet

- Simple Pump: The most accommodating fit in the CL range

- Iriza: D'Orsay construction changes pressure distribution; try before buying where possible

Key Takeaways

• Most CL pointed-toe pumps run narrow; many people size up half a size, but this varies meaningfully by model
• The So Kate has the most demanding fit in the range; the Simple Pump is the most forgiving
• CL uses EU sizing as standard; always know your EU measurement before buying pre-owned
• Patent leather does not stretch; soft leather can be professionally stretched by approximately half a size
• When buying pre-owned, the EU size stamped inside the shoe is more reliable than a converted UK size in a listing

Getting the size right matters for any pair of heels. For pre-owned Christian Louboutin, it matters even more: there are no returns, no exchanges, and no trying on first. The pair you receive is the pair you keep.

The standard advice everywhere else is a single line: "size up." That is not wrong, but in our view it misses the picture entirely. The So Kate and the Simple Pump share a brand. They do not share a last. This guide covers the real picture, model by model.

Do Christian Louboutin heels run small?

Yes, most styles run small relative to everyday footwear, and sizing up half a size is the right call for many people in pointed-toe pumps.

The reason is the last. Christian Louboutin uses a narrow, elongated last across most of its heel range. That construction creates the sleek silhouette the shoes are known for, and it also compresses the toes in the pointed section at the front of the shoe. If you are a true EU 38 in most other brands, an EU 38 in the So Kate may leave your toes with nowhere comfortable to go by hour two.

That said, "run small" is a generalisation. The degree depends on the model, the material, and the width of your foot. Some people find certain styles fit accurately at their true size. Others need a full size up. The consistent pattern: a narrow to medium foot can often manage the standard EU size in a pointed CL pump, though it will be snug at first. A wider foot needs to take sizing up seriously, and to consider which model is worth trying at all.

Are Louboutins true to size?

Not consistently, and the nuance matters. "True to size" depends on which style you are asking about.

For the So Kate at 120mm, the combination of an extremely pointed toe box and a high heel pitch means the foot is pushed forward into the narrowest part of the shoe. Most people find this runs at least half a size small. The Pigalle, also pointed but with a slightly different profile, often produces the same result.

The Kate family (70mm, 85mm, 100mm) has a rounder toe box and sits closer to true to size for a wider range of foot shapes. The Simple Pump is generally considered the most accurate fit in the CL range. Sandal and open-toe styles remove the toe-box compression issue entirely, and open-toe styles tend to fit more predictably.

"True to size" is model-specific. Always cross-reference with the official size guide at eu.christianlouboutin.com before you buy.

Model-by-model: how every major style fits

Each CL style has a distinct last shape, toe box profile, and fit character. These are not interchangeable.

So Kate (120mm): The most demanding fit in the CL range, and the one worth understanding before you buy. Sharply pointed toe, narrow last, high heel pitch. Sizing up half a size is the standard starting point. In patent leather, there is no stretch: if the toe feels tight at first wear, it stays tight. Suede and soft nappa develop a small amount of natural give over time. Full guide: Christian Louboutin So Kate guide.

Pigalle (85/100/120mm): A similar fit challenge to the So Kate. If you move between the two expecting a different experience, it will catch you out. Pointed silhouette, narrow last. Sizing up half a size is the standard recommendation. The Pigalle Follies, with its open shank, can feel slightly different at the ankle but shares the same narrow toe profile. Full guide: Christian Louboutin Pigalle guide. For a detailed comparison: So Kate vs Pigalle.

Kate family (70/85/100mm): The most forgiving of the classic CL pump lasts, and genuinely accessible for a wider range of foot shapes than the So Kate or Pigalle. A rounder toe box and more moderate heel pitch at lower heights make a real difference. If you find the So Kate difficult, the Kate 85 or 100 is often workable without sizing up. The Kate 70 is CL's most accessible pointed-toe heel and a sensible starting point if you are new to the brand. Full guide: Christian Louboutin Kate guide.

Simple Pump: Broader toe box, more rounded profile, closer to true to size for most people. The most forgiving fit in the CL pointed-heel range. A practical starting point for anyone with a wider foot who wants to wear Louboutin heels.

Iriza: D'Orsay cut, meaning the sides of the shoe are open. This changes how the foot is held. Many people find they can stay at their true size with the Iriza, though the open construction creates different pressure points than a closed pump. Fit depends on foot shape and arch height more than it does in a standard pump.

Do Louboutins run narrow?

Yes, and it is a characteristic of the brand across most styles. The CL last is built for a slender silhouette, which produces a narrower fit than mainstream footwear brands.

The So Kate is the narrowest. It is designed for a slim, elongated foot, and if you have wider feet, you will likely find it uncomfortable regardless of size. Sizing up helps, but it does not resolve the width issue fully because the last itself is narrow throughout.

Towards the more accommodating end of the range, the Simple Pump and styles like the Kate 70 have broader toe boxes that suit a wider range of foot widths. They are still slimmer than most high street footwear, but the difference is meaningful. If you have a D or E width foot, these are where to start.

Can you wear Louboutins with wide feet?

Yes, though model choice matters significantly. Several styles in the CL range are accessible for wider feet; the key is knowing which ones.

The styles that work best for wider feet:

• Simple Pump: The most accommodating fit in the pointed-heel range, with a broader toe box
• Sandal styles: Open-toe and open-side constructions remove the compression issue entirely
• Kate 70 and Kate 85: Rounder toe box, more forgiving than the So Kate or Pigalle

The styles to approach with caution for wider feet:

• So Kate: Very narrow throughout; width is a known issue even with sizing up
• Pigalle 120mm: Same narrow last, same limitations
• Any sharply pointed style in patent leather: No stretch, so first-wearing feel is what you will continue to feel

If you have a wider foot and want to wear CL heels, the Simple Pump gives you the red sole without fighting the last. If you are set on a pointed-toe pump, the Kate 85 or 100 is a better starting point than the So Kate.

Can you stretch Louboutins?

Soft leather, nappa, and suede styles can be stretched by roughly half a size by a professional cobbler using shoe stretching tools and solution. This works at the toe box and across the width, relieving pressure on the foot's widest part. It does not add length.

Patent leather is a different matter. The lacquer coating that gives patent its finish is significantly less flexible than uncoated leather. Overstretching patent risks cracking the finish, which is not reversible. Some cobblers will attempt a small amount of patent stretching, but the results are less predictable and the risk is higher.

The practical rule: for soft leather styles, professional stretching is a reasonable option if you are between half sizes. For patent leather, order the size that fits rather than stretching after the fact. Do not attempt to stretch Louboutins at home. The materials and construction require professional handling.

How do Louboutin heels fit?

The fit experience of a Christian Louboutin heel has a few characteristics that apply across the range, regardless of model.

Heel pitch. At 100mm and above, the angle of the foot is steep. This pushes weight forward onto the ball of the foot and into the toe box. At 120mm, such as the So Kate or Pigalle 120, the pitch is extreme and takes time to adjust to.

Break-in period. Leather Louboutins, particularly the classic pumps, are firm when new. The insole and upper need wear time to soften and conform to the foot. Most people find it takes two or three wears before the shoe stops asking for your attention. Pre-owned pairs that have already been worn are often more comfortable from the first wearing for exactly this reason. Someone else has already done the break-in work for you!

Toe compression. Pointed styles taper to a narrow front. The toe box houses the toes at an angle. This is a design feature, but it means getting the size right matters more in these styles than in a rounder-toe shoe.

Cushioning. CL heels have a relatively thin insole, designed for structure rather than extended wear. Most people add a discreet gel pad at the ball of the foot for longer events.

UK, EU and US size conversion

Christian Louboutin labels its shoes in EU sizing. When buying pre-owned in the UK, always check the EU size stamped inside the shoe rather than relying on a converted UK size in the listing.

These conversions follow standard industry sizing. Sizing can vary between styles and production runs, so verify against the Avantelle size guide and the official CL size chart before purchasing.

Buying pre-owned: getting the size right

When you buy pre-owned Christian Louboutin, you cannot try before you buy. Here is how to make a confident decision. At Avantelle, we find that getting the EU size right is the single biggest factor in buying pre-owned and having it work.

Know your EU size. CL stamps the EU size inside the shoe. This is the number that matters. Confirm it from listing photos rather than relying on the converted UK size in the product description, which may have been calculated from a non-standard table.

Measure your foot. Standing on paper, trace around your foot and measure from heel to the end of your longest toe. Match this against the official CL size chart to confirm your EU size before ordering.

Account for the model. If you know you size up half a size in pointed-toe heels, look for a pair in your adjusted EU size. If you are buying a Simple Pump, your standard size is a more reliable starting point.

If you are buying pre-owned without trying them on first:

• Measure your foot length carefully
• Confirm the EU size from listing photos, not just the product description
• Check the seller's notes on fit and wear history where available
• Account for the specific model's known fit profile

Pre-owned pairs that have been broken in can feel more generous than a new pair in the same size. The insole softens with wear and the leather at the toe box flexes slightly over time. This can work in your favour if you are borderline between two sizes.

Frequently Asked Questions

Do Christian Louboutin heels run small?

Most Christian Louboutin pointed-toe pumps run small relative to everyday footwear. The narrow last means most people need to size up half a size, particularly in styles like the So Kate and Pigalle. Models with a rounder toe box, such as the Simple Pump or Kate family, tend to run closer to true to size for a wider range of people.

Are Louboutins true to size?

It depends on the model. The So Kate and Pigalle run small for most people due to the narrow last and pointed toe box. The Kate family and Simple Pump are closer to true to size. Sandal and open-toe styles tend to be more predictable. Always verify your EU foot measurement against the CL size chart before purchasing.

Do Louboutins run narrow?

Yes, across most styles. The CL last is narrower than mainstream footwear brands. The So Kate is the narrowest; the Simple Pump is the most accommodating. If you have a wider foot, styles with a rounder toe box or open-toe construction are the ones worth looking at.

Can you wear Louboutins with wide feet?

Yes, though model selection matters. The Simple Pump, sandal styles, and the Kate 70 or Kate 85 are the most accessible choices for wider feet. The So Kate and Pigalle are built on a narrow last that does not accommodate width well, even with sizing up. Starting with a more forgiving style is the sensible approach.

Can you stretch Louboutins?

Soft leather and suede styles can be stretched by approximately half a size by a professional cobbler. Patent leather is significantly more resistant to stretching, and attempting to stretch patent risks damaging the lacquer finish. Do not attempt to stretch Louboutins at home.

How do Louboutin heels fit?

Christian Louboutin heels have a narrow last, a high heel pitch at 100mm and above, and a relatively firm insole. Pointed-toe styles push the foot forward into the narrowest part of the shoe. Most styles have a break-in period of a few wears. Pre-owned pairs that have already been worn can feel more comfortable from the first wear, since the previous owner has absorbed the initial break-in period.
