You’re not imagining it. Walk into most shoe stores with a size 12 foot and you’re looking at a handful of styles — if you’re lucky. The range genuinely is smaller, the frustration is real, and the reason isn’t bad luck or bad stores. Here’s what’s actually going on.

The Numbers
Women’s shoe sizes in the US follow a normal distribution — a bell curve centred around the middle, with progressively fewer women at either extreme. Analysis of over 1.2 million 3D foot scans published in Scientific Reports (2019) puts the average US women’s shoe size at 8.04, with a standard deviation of 1.52. NPD Group’s retail data shows what that looks like in practice: sizes 7 through 9 alone account for roughly 60% of all women’s shoe sales.
| US Women’s Size | Est. % of Women | Approx. % of Shoe Sales |
|---|---|---|
| 5 or smaller | < 1% | < 1% |
| 6 | ~2% | ~3% |
| 7 | ~12% | ~15% |
| 8 | ~22% | ~29% |
| 9 | ~22% | ~16% |
| 10 | ~15% | ~13% |
| 11 | ~8% | ~6% |
| 12 | ~3% | ~2% |
| 13 or larger | ~1% | < 1% |
Distribution estimates based on NPD Group sales data (2022) and foot anthropometry research (Scientific Reports, 2019).
Size 8 is almost a third of the entire market. Size 12 is roughly 2%.
This matters because of the last — the foot-shaped form a shoe is built around. Every size requires a completely separate last. You can’t stretch a size 9 last and call it a 12. Developing a new last from scratch runs $8,000 to $25,000, and a brand needs separate lasts for each size, each width variation, and each construction style.
When a brand sits down to decide which sizes to produce in a new style, they’re weighing those costs against a market that, at size 12, represents roughly 2% of potential buyers. Without malice — usually with genuine regret — they decide the numbers don’t work. Not this season. Maybe not ever. It’s not personal. It’s arithmetic.
The Old Retail Model Made It Worse
Layer the traditional retail model on top, and things compound.
A physical shoe store has finite floor space and a buyer whose job is to stock what the most people walking through the door can wear. In a typical city of 50,000 people, roughly 25,000 are women — and based on the distribution above, only about 250–300 of them wear a size 12. A shoe buyer can’t build a floor plan around 250 people when she has 24,000 others to serve first. So she doesn’t.
Which creates a self-reinforcing loop: brands only manufacture what retailers will order; retailers only order what they’re confident they’ll sell; extended sizes never appear on the floor; they don’t sell; brands scale back. Repeat. The loop that made size 12 feel like a secret category — something that technically exists, but that nobody seems to have in stock.
Why It’s Finally Changing
The old model was built for a world of physical stores serving a single postcode. Online retail breaks every assumption it depends on.
A brand selling online doesn’t stock one shelf in one town — it makes every style available to every extended-size shopper in the country at once. Those 250–300 women in our hypothetical town? Aggregate them nationally and you’re looking at roughly 5 million women who wear size 11 or above, and 2–3 million who wear size 12 or larger. That is not a niche. That is a market. A 2026 survey by AlixPartners found that 65% of shoe shoppers had walked away from a purchase because they couldn’t find their size. The demand has always been there. The supply is finally catching up.
There’s a structural tailwind too: feet are getting larger. The National Shoe Retailers Association found that the most popular women’s shoe size was 7.5 in the early 1980s and 8.5 by 2012 — and sizes 9 and 10 are the fastest-growing segments today. Brands building extended-size programmes now are positioning for the market as it will be. The ones making that bet are finding that the extended-size customer is loyal, engaged, and not at all accustomed to being well served. When you make someone a shoe that fits and looks incredible, they come back.
What Scarpe Diem Is Doing About It
Most size 12 options are scattered across dozens of brand websites and buried in search results. We curate them in one place — in stock, across every category — so you don’t spend an afternoon hunting. And every purchase signals to the industry that the demand is real: the only way to dismantle a model built on the assumption that extended sizes aren’t worth stocking is to make the market impossible to ignore.
