Size 13 Flip-Flops for Women: One Unisex Style
Quick answer: at UK 13 we found one style at one shop, and it may not be a true 13. The Havaianas Top in 45/46 is a unisex flip-flop on Havaianas’ women’s page, a doubled size charted as UK 12/13. That chart is an image we read through search results, and a second list gives 45/46 as about 11/12, so a true 13 fit is not promised. We found no women’s-labelled flip-flop or toe post at 13.

Thirteen is the end of the road for flip-flops, and possibly a step past it. One shop counts, one style counts, and the size that counts is really two sizes joined together. Every other range we read stops at 12 or before, and what appears at 13 elsewhere is a slide or a strap sandal. That is worth knowing before you spend an evening searching. If you need a true flip-flop at this size, the Top is what we found, and the chart decides whether it suits you.
We checked Havaianas’ product pages on 31 October 2026, and its size chart on 30 October. The chart is an image, so its figures rest on what we read there and on search result text. The other shops named here were read the same day to see who stops where, Next and Very before they refused further reads. Delivery and returns terms were read on 30 or 31 October. We did not check prices, and availability changes daily.
Where to buy size 13 flip-flops: 1 shop, unisex only
| Shop | At 13 (UK) | Type | Fits at 13 | Delivery and returns | Link |
|---|---|---|---|---|---|
| Havaianas | Unisex Top as 45/46, charted UK 12/13 | Flip-flop, doubled size | Not checked | Free delivery over £50 (site banner; charge below not read); returns within 30 days, unworn and unwashed with tags, with £4.90 deducted for drop-off or £7.00 for home pickup. | See the Havaianas Top |
The Top is unisex, shown on a women’s page. A 13 is the top half of its doubled size on one list and outside it on another. “Not checked” means we did not record that detail. Delivery and returns are the standard UK terms read on 30 or 31 October 2026, as shown in search results where marked.
The shops in more detail
Havaianas
The Top is the one style that counts at 13. It sits on Havaianas' women's flip-flops page, its own page calls it a core unisex style, and the default colour showed 45/46 as available. That is a doubled size, and on the chart we read a 13 is the top half of it. Havaianas does not promise a true 13 fit. Its site banner offers free delivery over £50, and we did not read the charge below that. Returns within 30 days must be unworn and unwashed with tags, and £4.90 is deducted for a drop-off return or £7.00 for a home pickup.

Why a true 13 is not promised
Two lists on Havaianas’ own pages disagree by one UK size. One gives 43/44 as UK 10/11 and 45/46 as UK 12/13, which matches our 30 October read of the chart. The other gives 45/46 as about 11/12, which would leave a 13 outside the size. Both reach us through search results, because the chart is an image. The chart’s centimetre row gives 29.1 to 30.3 for 45/46, in a row labelled Cent. (CM) rather than foot length. Long Tall Sally’s women’s chart gives 304 mm for a UK 13, just over the top of that range. So the figures are close, and they do not prove a fit either way.
What about 47/48?
Havaianas’ women’s filter runs on to 47/48, and the Top is listed that far. The first list charts 47/48 as UK 14/15, so it is not a 13 on that reading. On 30 October it showed as unavailable on a Top product page, and we did not confirm one as available on 31 October, so we do not count it.
Who stops below 13
- Crispins Shoes: its toe post reaches 12, and nothing above that was available.
- Birkenstock: the filter ends at 11.5.
- ASOS: the Crocband Flip ended at 11, and was sold out at 12.
- Crocs and Next: the Crocband Flip’s Women’s tab and Next’s Flip Flop filter end at 10.
- Marks and Spencer, FitFlop and Office: all end at 9.
- Simply Be, JD Williams and Shoe Zone: their toe posts end at 9. Their sandal filters run to 12, but at 10 to 12 Simply Be and JD Williams showed only Crocs clogs, and Shoe Zone’s items at 10 were clog sandals.

What else shows at 13
ASOS’s sandals at 13 were a strap sandal and adidas slides, and Next’s only sandal at this size was the adidas Green ZNSORY. Very’s sandal filter at 13 showed one adidas slider whose own product page stops at 8. Slides and strap sandals are not flip-flops, so none of these is on this page, and Very’s is not a real 13 of any kind.
How to measure your feet for size 13 flip-flops
Long Tall Sally’s women’s chart gives 304 mm for a UK 13, and it is here for length only, as it lists no flip-flop at 13. Havaianas’ chart gives 29.1 to 30.3 cm for 45/46.
- Measure both feet on paper, heel to the wall, in millimetres.
- Compare the longer foot with Havaianas’ own chart.
- Read the return terms first: Havaianas deducts £4.90 or £7.00 from a refund.
UK 13 in EU and US sizes
| Shop | EU | US | Foot length |
|---|---|---|---|
| Havaianas (doubled size) | 45/46 | Not given | 29.1 to 30.3 cm (row labelled Cent.) |
| Long Tall Sally (for length only) | Not read | Not read | 304 mm |
Havaianas’ chart repeats its own doubled size in the EU row, so 45/46 is not an ordinary EU label.

Frequently asked questions
Can I buy women's flip-flops in size 13?
Not with a women's label, as far as we found. The one style that counts is the unisex Havaianas Top as 45/46, a doubled size, so a true 13 fit is not promised.
Is a Havaianas 45/46 a UK 13?
One list charts 45/46 as UK 12/13 and another gives about 11/12. The chart is an image we read through search results, so read it on the shop's site.
Do Crispins Shoes' toe posts go to 13?
No. Nothing above 12 was available in its sandal collection.
Why are slides not on this page?
Slides are a different product from flip-flops. ASOS shows adidas slides at 13, but we do not count them as flip-flops.
Does ASOS list flip-flops at 13?
Not when we checked. Its sandals at 13 were a strap sandal and adidas slides.
Shops were checked on their own websites on 31 October 2026, and delivery and returns terms on 30 or 31 October 2026. Where we say so, details come from a shop’s own pages as shown in search results. We did not check Amazon UK’s listings.
