Size 11 Flip-Flops for Women: 3 Shops, Single Styles
Quick answer: at UK 11 we found three shops, each with a single route. ASOS shows the Crocs Crocband Flip in black, label not read. Crispins Shoes has one flat thong sandal, the Diamonte Rosso Hawaii in tan, with 11 the only size left. Havaianas’ women’s Slim as 43/44 and the unisex Top are charted as UK 10/11, so an 11 is the top of a doubled size. We found no wide fit we could confirm.

By 11 the word choice no longer applies. Crocs’ own Women’s size tab has stopped at 10, and Next’s Flip Flop filter returned nothing here. So what you have is a Crocs style that ASOS shows past Crocs’ own women’s tab, a thong sandal with a single size left, and a Havaianas size that covers two UK numbers. Each is a real listing, and each needs a look at the product page before you order. Only the Crispins sandal is labelled plainly as a UK 11 in a women’s range.
We checked these shops on 31 October 2026. ASOS’s product page, Crispins Shoes’ store data and Havaianas’ product pages were read directly, and Havaianas’ chart, which is an image, through search results. Next’s filter was read before Next refused further reads. Delivery and returns terms were read on 30 or 31 October. We did not check prices, and availability changes daily.

Crispins’ item is a flat thong sandal rather than a true flip-flop, and we count it as a toe post. Havaianas’ UK figures are a chart reading. “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
ASOS
ASOS showed the Crocs Crocband Flip in black at UK 11, available, in its women's sandals. Crocs' own Women's size tab stops at 10, and we did not read how ASOS labels this size, so do not take it as a women's 11. The seller and shipper is Gardiner Bros, so check the terms on the page. At 12 it was sold out. ASOS's own delivery is £4.50, free over £40 or with Premier. Its returns within 28 days are free for account holders under its Fair Use Policy, and £3.95 for guest orders.

Crispins Shoes
The Diamonte Rosso Hawaii in tan is a flat thong sandal, which the shop describes as having waterfall tassels, and 11 was the only size available. Treat it as last pairs. It is part of Crispins' large-size women's sandals, labelled UK 11, EU 45, US 13.5. Standard delivery is £6.50, free over £250. UK returns within 14 days must be unworn, and they are at your cost, as it offers no free return service.

Havaianas
The women's Slim has its top size at 43/44, charted as UK 10/11, and the unisex Top shares that size. An 11 is the top half of the doubled size, so a true 11 fit is not promised. As shown in search results, a second list puts 43/44 at about 9/10 and 45/46 at about 11/12, so read the shop's chart. 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.

Birkenstock: 10.5 and 11.5, but no 11
Birkenstock’s women’s thong sandals skip this size. The labels go from 10.5 (EU 45) to 11.5 (EU 46), and 11.5 is the top of the filter. Neither is an 11, so Birkenstock is not in the table, and we could not read its availability by size anyway.
Who stops before 11
- Crocs: the Women’s tab on the Crocband Flip stops at 10, though we did not open other flips.
- Next: one flip-flop at 10, and none at 11.
- Long Tall Sally, Yours and Evans: no toe post or flip-flop at 11.
- Simply Be and JD Williams: only Crocs clogs in their sandal lists.
Our size 10 flip-flops guide covers Crocs and Next.
Slides at 11
Next’s page at 11 showed adidas Adilette Aqua Sliders and Adilette Comfort 2.0, and Very’s sandal filter showed one adidas slider whose own product page stops at 8. Very’s filter has shown sizes that a product does not come in, so that slider may not exist at 11 at all. Slides are a different shoe from a flip-flop, and they do not count on this page.
What EU 45 means
The number changes from shop to shop at this size. EU 45 is a UK 11 at Crispins Shoes and on Next’s filter, but Birkenstock labels EU 45 as 10.5, and Long Tall Sally calls a UK 11 EU 44. So check the UK label and the shop’s own chart, not the EU number alone.
How to measure your feet for size 11 flip-flops
We recorded no flip-flop chart length at 11. For comparison, Long Tall Sally gives 288 mm for a UK 11 on its general women’s chart.
- Heel to the wall on a sheet of paper, on both feet.
- Mark and measure to your longest toe.
- Read the product page for the label, as these are single styles with their own sizing.

We pick from the facts in the table, not from prices or reviews, which we have not checked.
- A true flip-flop: the Crocband Flip at ASOS, checking the size label on the page.
- A women’s thong sandal labelled UK 11: the Diamonte Rosso Hawaii at Crispins Shoes, while it lasts.
- The largest women’s Slim: Havaianas’ Slim as 43/44, after reading the chart.

Frequently asked questions
Where can I buy women's flip-flops in size 11?
We found three routes: the Crocband Flip at ASOS, a flat thong sandal at Crispins Shoes, and Havaianas as 43/44, a doubled size charted as UK 10/11.
Do Crocs flip-flops come in a women's size 11?
Crocs' own Women's tab on the Crocband Flip stops at 10. ASOS shows the style at 11, but we did not read how it labels that size.
Is a Havaianas 43/44 a true size 11?
It is not promised. One list charts 43/44 as UK 10/11, which makes an 11 the top half, and another gives about 9/10.
Does Birkenstock have a size 11 toe post?
Not as a whole size. Its women's thong sandals have 10.5 (EU 45) and 11.5 (EU 46), and we do not call either an 11.
Does Next list flip-flops at 11?
No. Its Flip Flop filter returned nothing at 11, and the page showed adidas slides, which are a different product.
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.
