These are used, so they're perfect for practice if you need a lot of pairs. They've been washed, but please note that two pairs of white Nike Dri-FIT socks have artificial turf stains that won't come out, even after washing. This is a set of 5 soccer socks in various colors: - Color: Black, no brand - Color: Green, Adidas - Color: Red, Le Coq Sportif - Color: White x 2, Nike The size isn't indicated, so I'm not sure, but my son wore these when he was in 3rd and 4th grade. The width of the floor in the background is 9.5 cm. Please use this as a reference. Please understand that they will be simply packaged. I'm happy to answer any questions, and I'm selling these with no claims and no returns.
