Ash is a luxury-meets-streetwear brand best known for its edgy footwear, platform trainers, sculptural boots, and rock-inspired silhouettes. Since its launch in 2000 by French designer Patrick Ithier and Italian entrepreneur Leonello Calvani, Ash has gained a cult following among fashion-forward consumers across Europe and Asia.

But as with many premium brands, one question keeps popping up:

Does Ash run big or small?

In this detailed guide, we’ll uncover how Ash sizing really works for shoes, boots, and clothing—and how to find your perfect fit in seconds using Tellar.co.uk, the UK’s leading free sizing tool.


What Is Ash Known For?

Ash brings together Italian craftsmanship and Parisian design to deliver collections that blend luxury with rebellion. Their most popular items include:

  • Chunky platform trainers

  • Studded leather boots

  • High-fashion heeled sandals

  • Futuristic sneakers

  • Occasional clothing collections and capsule RTW pieces

Ash appeals to shoppers who want statement shoes with longevity—but buying the right size online can be tricky, especially when navigating EU, UK, and US size conversions.


Does Ash Run Big or Small?

Summary:

Ash footwear tends to run slightly small, especially in boots and structured sneakers. Clothing runs true to size, but is often designed for a slim European silhouette.

Now let’s break it down by product category.


1. Ash Footwear Sizing: Trainers, Boots, Sandals

Footwear tends to run:

  • Slightly small in structured styles (e.g. platform boots, wedge sneakers)

  • True to size in softer, flexible trainers

  • Narrow in the toe box for certain leather designs

  • EU sizing standard (e.g. 37 = UK 4)

Key Advice:

  • If you’re between sizes, size up—especially in pointed boots or leather high tops

  • Wide feet? Go up half a size for comfort in toe shape

  • Try on with socks in mind—Ash boots are designed slim and often don't allow much internal space

2. Ash Clothing Sizing: Coats, Tops, Trousers

Ash's ready-to-wear collections are less prominent but often follow seasonal trends in:

  • Oversized jackets

  • Moto-inspired trousers

  • Graphic tees and sweatshirts

Fit Summary:

  • True to size, but made for a European slim frame

  • Tops and jackets may have a boxy silhouette, but the shoulders and sleeves can run narrow

  • Trousers fit close to the body with a slightly cropped length

UK shoppers often find that Ash clothes fit:

  • Like COS or AllSaints, rather than looser UK high-street brands

  • More snug in structured woven pieces, true to size in jersey or knits


What Do Customer Reviews Say?

Shoppers and stockists (Selfridges, Farfetch, ASH.com) commonly mention:

  • “Gorgeous quality, but the shoes were too small—needed to exchange for next size up.”

  • “Size up if you're between sizes or want to wear socks.”

  • “The boot fits snug in the toe box; otherwise perfect.”

  • “Jacket was beautiful, but the cut is more fitted than I expected.”


The Issue: Sizing Isn’t Standardised

Ash uses EU sizing for footwear, and its clothing cuts are Italian-influenced. But not all styles conform evenly, especially across fabric types, design intents, and collections.

Common issues shoppers face include:

  • Confusion over EU-UK conversions (e.g. is EU 39 always a UK 6?)

  • Shoes that fit lengthwise but feel tight in the instep

  • Slim-fitting sleeves and shoulders in jackets

  • Incorrect returns due to misjudging the sizing model

UK vs EU Sizing: How Tellar Helps

Trying to convert an EU 38 into UK sizes depends on the style. Ash trainers may fit like a UK 5.5, while their boots might feel more like a tight UK 5.

Tellar automatically calculates:

  • Your best-fitting EU size

  • Which Ash styles run small

  • When to size up based on width and materials

Real-Life Example

Let’s say your foot length is 25cm, and you usually wear a UK 6 / EU 39.

Tellar detects that Ash’s leather high-top styles run short in the toe, and recommends a EU 40 for optimal comfort—saving you the pain of a misfire order.

Similarly, if your chest is 92cm and shoulders narrow, Tellar may suggest staying with S in Ash outerwear, but going M in tailored pieces.
