Thanks for the "last" pics. I have shoes and/or boots on all four of those lasts.
Are you saying in your experience the 202 and 888 are wider than the 606? That is interesting .....
Belgravia? Beautiful shoe.
I have shoes on the 888E/F and 202D lasts. I didn't size down for the 184E, and I don't think I could've done so either.
Good luck with your purchase!
