GIVENCHY Logo-print rubber slides | NET-A-PORTER。Givenchy Slides in Size 42 IT Unisex in Black with Givenchy in White These are technically men’s shoes in a Size 9, so are a women’s 11. See my international shoe sizing explanation below: Sellers seem to always say EU 41 is a US Size 11, but I’m an 11 and I require a size larger - EU 42. Italian sizing uses the same numbers as European sizing and many sellers get them confused, so be careful! So I require a Size IT 41/EU 42/US 11, but all feet are different. To be absolutely certain, measure your foot in centimeters and refer to the different countries’/regions’ size charts, but be aware that a seller can easily confuse EU and IT shoe sizes! So you must ask them for the shoes internal CM measurement as well. I am providing you the information I have being a true US Size 11 in all shoes and having tried on my listings, I know whether it’s EU or IT sizing based on fit! My findings: these DO FIT my Size 11 (27 cm Length - at longest- and 8.75 cm Width - at widest) feet! Please let me know if you have any questions! It IS confusing, so I’m happy to help! In this case, you’d also have to refer to men’s EU and IT and US charts and then convert to women’s, but the US listing sizes that I provided are pretty accurate here for men and women! Please let me know if you have any questions though! It IS confusing, so I’m happy to help! Comes with box.
