How to Find Your Size in Ash

By Ella Blake | Tellar Fashion Hub

Quick answer: Ash footwear generally runs true to EU size for most styles, but their iconic wedge trainers and chunkier sneakers tend to come up slightly large — sizing down half a size is often the smarter move.

Ash is one of those brands I discovered embarrassingly late — and then immediately couldn't stop wearing. That very first pair of white leather Addict wedge trainers nearly broke my budget, but the moment I had them on I understood completely. They're not just shoes. They're a whole attitude. The problem? Getting the sizing right the first time. Because Ash, being a French brand with Italian production, doesn't always play by the same rules as your usual high street trainers. I've learnt this the hard way — and I'm going to save you the same mistake.

Understanding Ash as a Brand

Founded in France in 2000, Ash has built its name on rock-and-roll-inflected footwear — think biker ankle boots, studded leather slides, chunky platform trainers, and their signature wedge sneakers that practically launched an era. The brand bridges that interesting space between luxury and wearable: premium Italian leathers, proper construction, but designs that feel genuinely cool rather than try-hard. The customer base is broad — I see Ash on everyone from 25-year-old creatives to 50-somethings who'd rather die than wear a boring shoe.

The sizing is predominantly European (EU), with UK and US conversions available. Most retailers stock EU 36–42, which covers UK 3–8. The quality and structure of the leather means fit can vary quite meaningfully between different silhouettes — so let's break it down properly.

Do Ash Shoes Run True to Size?

Generally speaking, yes — with some important caveats by style:

Wedge trainers (e.g. Addict, Bowie, Maiko): These are the Ash classics, and in my experience they run slightly large. I'm a consistent EU 38 in everything from Reiss to Massimo Dutti, but in the Ash Addict I found a 37.5 to be my perfect fit. If half sizes aren't available, size down to a whole size — the leather will soften with wear and you don't want to be swimming in them.
Biker ankle boots: These tend to run true to size but feel snug across the ankle initially. Don't panic — the leather breaks in beautifully. Stick with your regular EU size and give them 2–3 wears.
Flat trainers and low-profile sneakers: These run true to size or occasionally slightly narrow. If you have a wider foot, consider going up half a size.
Heeled styles and sandals: True to size. I've had no surprises here at all.

My Personal Sizing Experience

I ordered a pair of Ash Bowie trainers online in my usual EU 38 after reading approximately forty reviews and convincing myself I'd cracked it. I had not cracked it. They were a solid half size too big — fine with thick socks in autumn, but uncomfortable in summer and frankly a little sloppy-looking. I swapped for a 37 and they were perfect. Lesson: for the wedge and platform trainer styles specifically, don't assume your standard size. The slightly roomier last that makes them comfortable over long distances is actually working against you if you go too big.

On the flip side, the Ash Witch ankle boot I bought the following year in my normal 38? Spot on. So the style really does make a difference.

Width Fit: Is Ash Suitable for Wide Feet?

Ash generally cuts to a standard or slightly narrow last. For wide feet, I'd recommend:

Going up a half size from your usual EU size
Trying styles with elasticated panelling or adjustable straps, which accommodate more width
Avoiding the very sleek, pointed biker boot styles, which will be unforgiving on broader feet

If you're between sizes, Ash customer service is genuinely helpful — don't hesitate to reach out via their website before buying.

Where to Buy Ash in the UK

Ash is stocked through a solid range of UK retailers, both online and in-store. Here's where I'd look:

ASOS — Probably the easiest place for size comparison and free returns. Particularly good for wedge trainers and their core trainer styles.
Reiss — Stocks a curated edit of Ash's more polished styles; great for the ankle boot silhouettes.
Ted Baker — Occasionally carries Ash in multi-brand edits; worth a check for seasonal drops.
Anthropologie — A lovely place to find Ash alongside other directional footwear; the edit tends to lean into their quirkier, more feminine styles.
All Saints — Stocks Ash edgier boot styles that pair brilliantly with their leather jacket aesthetic.
Whistles — Occasionally carries Ash flats and loafers for a more refined take on the brand.
LK Bennett — Known for stocking Ash heeled styles for smart-casual occasions.
Cos — Occasionally features Ash in collaborative edits or in-store pop-ups; check seasonal drops.

Two independent brands worth knowing if you love the Ash aesthetic:

Miista — A London-based independent label with serious craft credentials and a similarly rock-inflected edge. The leather quality is exceptional and the sizing is consistent EU true-to-size. If Ash is your vibe, Miista will be a revelation.
Clergerie — A French heritage shoe brand with incredible construction. More elevated in price but extraordinary in quality. Their trainer and platform styles appeal to exactly the Ash customer who wants to step things up.

How to Convert Your Ash Size

Ash uses EU sizing as its base. Here's a quick reference for converting to UK sizes:

EU 36 = UK 3
EU 37 = UK 4
EU 38 = UK 5
EU 39 = UK 6
EU 40 = UK 7
EU 41 = UK 8

Bear in mind these are general conversions — always check the specific Ash size chart on whichever retailer you're shopping, as conversion can vary slightly by stockist.

My Top Styling Tips for Ash

Ash footwear has a very specific visual language — it's about contrast and a little controlled rebellion. Here's how I like to wear them:

Ash wedge trainers + tailoring: Absolutely my favourite combination. A wide-leg trouser from Mango or Me&Em with a fitted blazer, broken up with the wedge trainer underneath. It's that fashion-girl mix of dressed-up-dressed-down that never really goes out of style.
Ash biker boots + midi dress: A feminine midi from Phase Eight or Hobbs with the Ash biker boot creates a brilliant tension. Tuck in slightly at the hem for the right balance.
Ash slides + wide-leg denim: Classic. Grab a great pair of Levi jeans and let the slides carry the look. Zero effort, maximum polish.
