Thanks so much HunI'm glad you did not end up buying the cheaper priced shoe before trying the fit. Have you tried Chloe's actual business website? They carry half sizes.

They are super tight around my forefoot. I'm just hoping they will loosen up! Yeah I have but they are about 2000AUD to me plus customs. I paid $1480AUD including customs from ssense. I missed out on the last pair of 38.5 from farfetch only by a few hours. I am a true 38.5. Are they supposed to be quite snug (uncomfortable but not painful) initially before they wear in? Don't want to get half size bigger and they be slipping off. Do you happen to know how much they stretch?
