Hello, I am ordering a pair of shoes for myself and one for a colleague from Pediwear. As I am a 13 US and they don't carry half sizes, I am going to try the Highgrove in a 12F UK and hope for the best. My colleague, however, is a much easier-to-fit 10D US. He is piggybacking on my shoe obsession, but is concerned about getting the right size the first time. Carol at Pediwear recommended a 9.5F, but I have heard that for C&J non handgrade going down a full size is often a better idea. Given that the Sargents are F fitting, would a 9F be a better choice? I'd particularly like to hear from Dr. Bresch, as the Wigmores are Premier line shoes, which seem to be almost all F-fitting. Thanks.
