What size would you recommend in AS? Size down 1/2 step or a full step from my US size? In particular, I'm interested in the Holborn.
My "true" US size is a 10.5D. I wear the Allen Edmonds Park Avenue in an 11, however, because of its low in-step. I've got the Ralph Lauren/C&J Darlton Wingtip in a 10.5.
I'm hoping it's 1/2 size down, because the Holborn is in stock at a UK 10, but not 9.5.
