These sandals are made of breathable mesh material for a comfortable fit. They have been washed at home, so I think you can wear them comfortably. - Brand: Nike - Model Name: Rift (GS/PS Boys) - Color: Black/White - Size: 12C (UK 11.5) 18cm Thank you for viewing. These were worn by a child, so I will sell them to someone who understands this. They were worn for one season, along with other sandals, so there are no noticeable major scratches, but there may be some scuffing. Please refrain from purchasing if you are concerned about minor details. #Nike18cm #SportsSandals #KidsShoes18cm
