Sperry Pink Flip Flops

There is no size on the shoe. I wear a 9.5 and there is still toe and heal room. All measurements approximate Length straight down the center is 10.5". The toe area is slightly higher from where I measured from. See picture. These have been worn a few times and have some marks on the foot bed. Still have a lot of wear left in them. I'm going to say it is all man made materials although shoe is not marked as such.
