NIKE Air Max 90 Gore-Tex Sneakers Size: 12 (30cm) Color: White/Gray These run a bit small, so for reference, I usually wear 28cm or 28.5cm in other sports shoes. I mainly wore these on rainy days, so there is some wear and dirt on the outside, but the inside is still in good condition. I think you can still wear them on rainy days and snowy days in the winter. Please understand that these are used items.
