- Perhaps this is obvious, but I will also note that click-and-mortar merchants like Bespoke England and Skoaktiebolaget offer extremely helpful sizing advice. If you tell them how other makers' lasts and sizes fit you, they will recommend a size for G&G. While an online order is also risky, I have had 100% success with the advise from both of these merchants for sizing in G&G, Carmina, and St. Crispin's.
So, I guess my advice is, when you are ready to make another shoe purchase, try these venues too. If you get a shoe that does not fit, you can recoup much of your money reselling a mint shoe here, and you should then know what your size is. The loss is cheaper than a trip to London for most.
