Apologies if this has been covered before. Just wondering if anyone is familiar with the sizing for the C&J Chelsea boot on the 238 last, before I make an online purchase. For reference, I take a US 9 (42) in Mantellassi, US 9 in Santoni. I have a pair of Polo chelsea boots (made in Italy, not C&J) that are US 9.5 and they are a tad snug. Any comments are appreciated. Thanks.
