Quick Answer

Size 15 trainers are hard to find on UK high streets but easier online: Nike, adidas, New Balance, ASICS and Skechers all make UK 14-15 and beyond in selected models, and Foot Locker UK, JD Sports and specialist big-size retailers stock the widest ranges. The unexpected trick is resale - big sizes often sell below retail on StockX, GOAT and eBay because the buyer pool is smaller.

If you wear a UK 13 or above, you already know the routine: you find a trainer you like, click the size dropdown, and watch it stop at 12. Retailers order sizes in proportion to demand, and demand falls off a cliff above UK 12 - so shops that carry hundreds of pairs in size 9 might stock two in a 14. The pairs that do exist sell out fast precisely because so few were ordered.

The practical consequence is that big-size trainer shopping is an online game. High street shelves rarely go past 12; the online warehouses of the same retailers carry the full size run. Knowing which brands actually manufacture the bigger sizes - and which retailers bother to stock them - is most of the battle.

Big size conversion table

First, the conversions, because international listings and resale sites display US and EU sizes. The bigger your feet, the more important it is to check the centimetre measurement too, since it is the one scale every brand shares.

UK, US, EU and CM sizes at the big end
UKUS (men's)EUFoot length (cm, approx)
UK 12US 13EU 47.530 cm
UK 13US 14EU 48.531 cm
UK 14US 15EU 49.532 cm
UK 15US 16EU 50.533 cm
UK 16US 17EU 51.534 cm

Brands vary by half a size in practice, so measure your foot in centimetres and compare against the brand's official size guide before ordering - the size charts on our tools page give the general conversions across men, women and kids.

Which brands make the biggest sizes

  • Nike - many mainline models run to UK 14 (US 15) online, and basketball shoes often go further. Air Force 1s, Dunks and Air Max are the most reliable for big sizes.
  • adidas - similar range, with UK 14+ available in most mainline models online including Sambas, Gazelles and running lines.
  • New Balance - one of the best for big and wide feet; many models go to UK 14-15, and NB's wider fit suits bigger feet well.
  • ASICS - strong on sizes through UK 13-14 across the running and lifestyle ranges.
  • Skechers - frequently reaches UK 14+ and runs wide, making it a comfortable option for bigger feet.
  • Converse and Vans - go big (often UK 14-15 in Chucks and Sk8-His), though the narrow, flat fit will not suit everyone.

The pattern: the big American brands and basketball or running lines carry the deepest size runs. Slim, fashion-led models are the least likely to be made above UK 12-13.

UK retailers that actually stock big sizes

Online, Foot Locker UK and JD Sports carry the widest big-size selections across Nike and adidas - use the size filter, since it hides everything unavailable in your size. size? and the brands' own sites reach similar ranges. Sports Direct covers budget lines in big sizes too.

Beyond the mainstream, specialist big-size shoe retailers operate online in the UK specifically for sizes 13 and up - worth a search if the big brands' ranges do not cover what you want. And Amazon UK carries extended sizes across Skechers, New Balance and adidas that the brand sites sometimes lack.

The resale trick that works in your favour

Here is the genuinely counterintuitive part: big sizes are often cheaper on resale. Resale prices follow demand, and the buyer pool above UK 13 is small - so while a hyped colourway resells for a fortune in size 9, the same shoe in a size 15 frequently sits at or below its original retail price.

On StockX, GOAT and eBay UK, filter by your size first, then sort by price - and factor in buyer fees, shipping and any import charges to get the true delivered total. For sold-out colourways, resale may be the only place your size ever existed in meaningful stock.

Practical tips for buying big sizes

  • Filter by size first - always set your size before browsing. It hides the heartbreak of falling for a shoe that was never made in your size.
  • Check CM, not just UK - brands vary by half a size, so your foot's centimetre measurement is the reliable constant.
  • Look at running and basketball lines - these carry the deepest size runs; slim fashion models rarely go big.
  • Buy junior-to-adult boundary carefully - irrelevant at this end, but know that US sizing on resale listings is men's unless stated.
  • Do not sleep on restocks - big-size allocations are tiny and rarely restocked, so when your size appears at a fair price, waiting for a bigger discount often means missing it entirely.
  • Consider the 'half size down' myth carefully - some brands run generous in big sizes, but never assume; check model-specific fit notes first.

One more honest note: sale sections are thinner in big sizes simply because fewer pairs existed to begin with. The trade-off is that when a big size does hit a clearance rail, it sometimes sits there longer than the popular sizes did - patience can pay, but alerts beat patience when stock is this scarce.

Get alerted when your size appears

Big sizes sell through fastest precisely because stock is thinnest, so checking manually is a losing game. On Sneaker Pingz, save the pair and your size to your favourites, register your email, and we will ping you the moment it appears at a UK retailer in your size - before the handful of pairs are gone. The trainer sale hub shows which retailers are discounting right now.

Frequently Asked Questions

Where can I buy size 15 trainers in the UK?

Online is where the range lives. Foot Locker UK and JD Sports carry the widest big-size selections across Nike and adidas, the brands' own sites stock their full size runs, and specialist big-size retailers cover sizes 13 and up. High street shelves rarely go past UK 12.

What is UK size 15 in US and EU sizes?

A UK 15 is a US 16 and roughly EU 50.5, fitting a foot around 33cm long. Because brands vary, always check the centimetre measurement against the brand's official size guide - the CM scale is the one every brand shares.

Which trainer brands make size 15?

Nike, adidas, New Balance, ASICS and Skechers all reach UK 14-15 in selected models, with New Balance among the best for big and wide feet. Basketball and running lines carry the deepest size runs, while slim fashion models rarely exceed UK 12-13.

Why do big trainer sizes sell out so fast?

Retailers order sizes in proportion to demand, so a shop stocking hundreds of pairs in size 9 might carry two or three in a 14. Those tiny allocations sell through quickly and restocks are rare - which is why availability alerts matter more for big sizes than any other.

Are size 15 trainers cheaper on resale?

Often, yes - resale prices follow demand and the buyer pool above UK 13 is small, so the same hyped shoe that resells at a premium in size 9 frequently sits at or below retail in a 15. Factor in buyer fees and shipping when comparing the delivered total.

Do wide feet need different trainers in big sizes?

Often - length and width are separate problems, and many people with big feet also run wide. New Balance is the standout brand since it offers wide fits and reaches UK 14-15 in many models. Skechers also runs generously wide. Check each brand's fit notes before ordering.
