Nine West, Victoria's Secret, Newport News - a lot of the low-to-mid range ones; occasionally couture zappo will have a 10.5. Also, DesignerShoes.com goes up to 12 sometimes with Stuart Weitzman, Claudia Ciuti, and Via Spiga.
i know for sure christian dior and manolo blahnik do up to size 12. i believe that dior maybe even do up to 12.5, but i'm not completely certain. the size 11-12.5 aren't widely available in the boutiques (i know the saks fifth avenue here in town doesn't carry sizes bigger than 10, and maybe sometimes 11) but you can defintiely special order them from christian dior or manolo. i believe christian lobuoutin does up to a 12 as well.
don't some designers also offer a service where you can order shoes made to the exact measurements of your feet?
and what about women with wide feet?
i've been thinking this. don't women with wide feet deserve designer shoes, too?
i really don't understand why most designers don't do in wide widths.
