I'm not sure if they changed anything so I'm sending it back for an exchange. I've been ordering Bostonians for years and love them. The latest version is so tight I can't walk without severe pain. . . . I can't even sit without severe pain. I ordered 10.5M and that's what it says on the shoe but when I removed the foam insert it was labeled 9.5. So maybe it was a mislabeled copy. (Or maybe earbuds always come in different sizes?) Fingers crossed, the exchange gets better.
