I've worn these a couple of times, but the size doesn't quite fit, perhaps due to the 3D design. I'm selling them because they were expensive socks. There are a few minor stains and some slight fabric wear, but only a little, so please be aware of that. I usually wear 23.5cm shoes and have wide feet, but these were a bit big on me. I think they might fit someone who wears 24-25cm. They are marked Left and Right. They might be more suitable for men. I think these would be good for someone who likes Nike or already owns similar 3D-style socks. For reference, I've included photos comparing them to regular 23.5-24.5cm socks and a photo with a measuring tape. It might not be very helpful, but please take a look. Please make your own size judgment. #Nike #Sportswear #SportsSocks #NikeSocks #RunningSocks #RunningWear #BlueSocks #3DSocks #AnkleSocks #TennisSocks
