Re: C&J UK v. US sizing - from the mouth of C&J's own inimitable Mr. Huqstable (March 2010):
Thank you for your e-mail, I trust that you are well.
We do indeed make the Darlton bluchers, for Ralph Lauren in dark
congnac shell cordovan.
A US size 12 D is a UK size 11.5E in the last 325. Should you opt for
a shoe form our Handgrade range a full size down (11E) is recommended.
