Anyone out there have experience with Rachel Simpson shoes? I am a 7.5 and the designers site (U.K) says "shoes run true to generous so 1/2 sizes order a size down." But the U.S. website says "we recommend 1/2 sizes order a size up and use a shoe insert for comfort." That doesn't sound ideal. lol. Anyone own a pair, and if so what do you think of the fit? Thanks!
