Walk into most shoe stores, and you're lucky to find any women's shoe larger than a size 10 - and the retailers that do carry large-sized women's shoes find them selling out faster than ever before.
However, buying shoes for women who wear larger shoe sizes is now a much simpler process, thanks to the web. Below are a few online shoe stores that carry larger sized women's shoes. Be sure to check size charts, and the location of the store, since sizes can vary from country to country.
DesignerShoes.com
Large Size Women's Shoes in a Broad Selection of Widths
DesignerShoes.com carries quite a decent selection of larger-sized women's shoes in U.S. sizes up to 15, including many styles with high heels. But the best news is, they also have many styles that accommodate extra narrow or extra wide feet in those large sizes as well. (Buy Direct)
Zappos Shoes
Great Selection in Large Size Women's Shoes
Of all the shoes stores listed here, Zappos (U.S. based) had by far the largest selection of women's shoes in sizes up to 14 (U.S). In fact, when I searched for size 14 casual women's shoes, over 120 results were returned, and nearly 150 dress shoes were available. Zappos does carry even larger women's sizes, although the selection beyond U.S. women's size 14 is far more limited. (Buy Direct)
DreamShoes
Fabulous Shoes in Sizes 10-15
With lots of casual and dress shoes to choose from, women who wear a larger shoe size will love this site. I'm particularly impressed with their selection of dress shoes, which includes some very pretty styles from brands like Magdesians, Pelle Moda, and Moda Spana.(Vendor's Site)
Barefoot Tess
Great Selection of Unique Shoes
With shoes from the likes of Jeffrey Campbell, LuLu Guinness and Via Spiga, Barefoot Tess is a site that you definitely won't want to miss. Carrying sizes up to U.S. 13, this site has an incredibly large selection of incredibly hip shoes. Instead of just offering what is already available in larger sizes, Barefoot Tess has cute shoes manufactured just for them. This site is a must stop for women who wear large sizes and want pretty shoes and boots. (Vendor's Site)
Cinderella Shoes
Large Size Women's Shoes from Ireland
Cinderella Shoes is an Ireland-based shoe retailer, specializing in large size women's shoes. Though the selection is not quite as large as some of the other retailers on the list, they carry a nice selection of larger sized women's shoes, and have size and price conversions built right into the page.

Lush Shoes
Divine UK Finds in Large Size Women's Shoes
Based in the U.K. and carrying U.K women's sizes from 8-11 (approximately 10-13 U.S. or European 42-46), Lush Shoes is a smaller site, but has fabulous looking shoes at moderate prices. Although many items are not available in all sizes, or were out of stock when I visited the site, their shoes are so nice looking, it will probably be worth it to check back often, or contact them about your size.
