Dang. Tried on my new G&G double monks last night (they had arrived via UPS). At 9.5UK, they are just a tad small. Very tight across the vamp - I can't do up the front buckle - and slightly cramped in the toe box.
Good old shoe sizing. I take a 9UK in Loake Bedales, 9 to 9.5 in Santoni, 44EU in various low-end brands. "It just don't add up."
So, back they go, uncreased, unscuffed and in mint condition. Dean is holding onto a replacement pair for me at size 10.
ps - at least I know my size in G&Gs now...
