Crocs Women's Sandals These have a heel, so they don't slip off easily. Great for clamming, the pool, and the beach! Used them in Hawaii. Dark brown with pale pink rubber. I don't remember the size exactly, but I think it's around 22.5 to 23.0 cm. Very light! The inside of the heel is a little worn. For those who understand that this is a used item. Beach Pool Clamming
