Does anyone have any idea of how Lanvin heels booties/pumps sizing runs nowadays? I tried searching the forums but only found *current* info on flats. I'm looking at 2 pairs of heels: one patent, one regular leather. I'm a US 7. (Most designer: 37.5-38) I'm thinking .5 up on leather, 1 full on patent? I can't try these on at a store (local stores have really limited inventory) and hope you could share your opinions. Thanks!
