Thanks for the quick response. If you went down two sizes as a D in AE, that gives me some comfort that going down 1 size as an E would probably fit my foot.
I just really, really like the two tone stuff he is doing and the forest green calf/suede combo caught my eye. You don't get options like that or Alden or AE,
Just to be clear, in US sizes, I am a normal width 8 in AE and a normal width 7 in J. Fitzpatrick, so it would be "one size down", not two. Also, as I noted, I don't know the lasts for AE at all, so can't comment on how they fit compared to Justin's.
