I connected with Yenni about a pair of unlined snuff chucka boots and provided the following sizing info:
I'm typically size 11 average width TTS.
I wear average width 10.5 in Barrie and Trubalance and flex sole Van loafer, and 11 in Hampton.
Grant shell boots in 11 were tight across the top of my foot but length was good.
Based on this she recommended 11 E in the Leyden last because it's tighter in the toebox.
I'll take Yenni's advice but am curious whether any of you with average width feet take E width in the Leydon last.
EDIT - Ugh...A simple search of this thread shows this has been covered and most seem to follow the advice provided to me by Yenni.
Leffot only orders E widths in the unlined chukkas.....from their site:
Sizing: The Leydon Last runs narrow. We recommend ordering one width wider than your standard US size.
