TheShoeSnobI have worn US10D in the past but it is dependent on the width of the last used? if the showbox is narrow, I cannot wear in a US10D comfortably.
WPP007our shoes are quite true to size, definitely not narrow. But it is hard for me to give you a confident answer. If you can fit AE Park ave in US10D then you can easily fit ours. If you can fit a Crockett & Jones UK9E then you can fit ours too.
