Newborn Denim Bow Sandals

Denim sandals with bow for newborns. Flexible rubber soles.. New with tags. Tag says Size 0-6 months, but when I originally bought for my 4 month old, they didn't fit (she might've just had fat feet, lol). But I'd say these are more Newborn, to possibly 3 months size. Cardboard still inside keeping the shape of the sandal.
