I had these in my 10 but they were too loose - slipped in the heel. I have 9.5 and it fits like a dream. I've been wearing this style since the 1990s, it's classic, simple loafers. Suitable for jeans, trousers and skirts. For those with custom orthotics, I have graphite orthotics and mine fit a B or medium/regular width perfectly with no issues. So comfortable and classic.
