I ordered these a size larger than I would wear due to the fact that they were only medium width. I also have a high arch, which makes getting new shoes difficult. But I am so glad I ordered them. They are SO pretty! I love how they look and feel on my feet, they fit like a glove. I expect to have to work a bit to get them on/off due to my high arch, but other than that, they are great. I would definitely recommend them, even if you have a larger than normal foot, if you order up.
