Balenciaga Leather Flip-Flop Sandals in Black Size IT 41/US 11 New. Never worn. 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!
