At 12 a safety boot is easier to find than you might expect, because unisex ranges reach this size as a matter of course, and Amblers and Toolstation both still have a list. The boots are the same ones you would find if you had never looked at a women’s page, so it can help to go straight to Amblers’ collection or Toolstation’s unisex page. Screwfix’s women’s list shows only wellies, and the Shoe Zone filter that reaches 12 holds a safety trainer.

We checked each shop’s own website on 31 October 2026. Amblers Safety’s store data, Toolstation’s unisex page and Screwfix’s women’s filter were read directly. Arco’s details come from its own pages as shown in search results. Delivery and returns terms were read on 30 October. We did not check prices, and availability changes daily.

Women’s filters at size 12

Amblers Safety: the Sophie Collection, its women-only line, ends at 9, and the boots under Womens at 12 are unisex styles.
Toolstation: we found no Womens boot above 9, as its women’s safety footwear page gives sizes 3 to 8 and its Womens size 10 address is a 404.
Arco: the women’s styles we saw stop at 8 or so.
Workwear Gurus: 9 is the largest size in its Womens Safety Boots filter.
Screwfix: its size 12 page for women held the same non-safety Cotswold Windsor Tall wellies.
Shoe Zone: its filter reaches 12, but only a unisex EarthWorks safety trainer can hold it, not a boot.
Dr. Martens and CAT: neither’s own UK shop has a safety-toe boot. Dr. Martens’ work range is slip-resistant, with a filter to 13.

What we noted at 12

The list we noted at Amblers has no AS501R at 12, and the AS240 only in black. At Toolstation, the boots we noted include the Amblers FS218, while the AS308c and Cofra Summit we noted at 11 were not among them, though we named only part of each list. Between them, the lists still cover a dealer boot, a hi-leg, a wide fit and several brands. Toolstation’s page at 12 has the Stanley Cascade, which we did not note at 13.

Compare the AS241 before you order

Amblers Safety and Toolstation both list the Amblers AS241 at 12, on different terms. Toolstation delivers next day for £5, free over £40, and charges £9 if it has to collect an unwanted pair. Amblers Safety charges £3.99, free over £75, delivers within 3 to 5 days, and leaves the return postage to you. Arco’s Essentials boot is a third route to a waterproof unisex boot, as shown in search results, though we could not see whether 12 was available. Amblers Safety’s page puts its widest choice between 4 and 9, and the list we read at 12 was shorter than at 9.

Measuring and width at size 12

We did not record a foot length from these shops. For a length to compare with, Long Tall Sally’s women’s chart gives 296 mm for a UK 12, and Dr. Martens’ chart, which covers its unisex sizes, gives 31 cm. We did not record EU or US sizes for these boots.

Measure both feet in the evening, when they are at their largest, and use the longer one.

Most boots at 12 are standard fit. Amblers’ AS803 Broad wide fit boot is on the list here and runs to 14, and Arco’s Foot Width filter offers Regular and Wide. Amblers has a 12.5 on one style only.

Our picks for size 12

We pick from the facts in the table, not from prices or reviews, which we have not checked.

A dealer boot: the unisex Amblers FS165.
A wide fit: the unisex Amblers AS803 Broad.
