New Givenchy City Platform Low Top Sneakers Size EU-IT37, UK4.5, US6.5. Actual fit is half to one size bigger for usual EU37. This pair of sneakers would fit EU 37.5 to 38. My usual size is EU-IT37 with most Givenchy sneakers but this one came out bigger than my usual shoe size. RRPĀ£637+ but selling for a much cheaper price (negotiable).
