I posted this question in the C&J thread but got no love. So, I'll make it into a general English shoe question.
I own 5 pairs of English shoes & 2 pairs of boots. 4 of 5 shoes (2x AS, 2x Cheaney, all avg width) are a little narrow & rub at the instep. The only exception is the very generous AS 7WK last. Both pairs of boots (1 Barker F, 1 Hogg by Cheaney G) are super comfy. Should I go up a width (F, or is it G?) for future English rtw shoes? or will I be swimming in them? I guess the question is, how much difference is there between English shoe widths?
