Authentic Louis Vuitton Stellar sneaker

They’re a size 38. They run a little big. I believe they would fit someone who’s a 8 or 8.5. I got them as a gift, but they’re lose on me and I’m a size 7.5 and 8 sometimes (US). I cannot return them because it’s past their 30 day policy. They’re like brand new, only worn ONCE and at home. impeccable condition. No stains no marks no scratches, nothing.
