It just say the number. These are adorable and feel very soft. I usually wear 8-1/2-9 but found the 10M fit more comfortably. I thought they would be hard for my 20 mo. I think the only reason I see it with my shirt on is bc I know its there. Really cute, but terribly uncomfortable. Second, the rubber tracks do not stay in easily. 1 fish, 2 fish, buy these shoe fish! Ive gone through a lot of mice during my time as a gamer. I dont hang anything heavy on them.
