Color: Black系 (likely meaning black or shades of black) Size: I believe it was 27.5. The size isn't indicated on the product itself, so I'm estimating based on my usual shoe size as 27.5. I will accept returns if the size doesn't fit. (The buyer is responsible for return shipping costs.) The only noticeable dirt is some black scuffing on the white rubber sides, but it's not very prominent. I've only used these 2-3 times in my yard, so there's no wear on the soles. If you're interested, please feel free to comment.
