These are knitted with a very soft variegated cotton mix yarn. They have anti-slip dots on the soles. I put a ribbon through the top of the booties which are tied in the back. If the slipper needs to be more tied on the toddlers foot you can do so with the ribbon. The big bows on the front of the slipper are made of a cashmere mix fabric and decorated with a pretty button. Size: They measure approximately 5 inches from the toes to the heel but have about a 1 - 1 1/2 inch stretch. They are approximately 3 inches wide. According to my chart these should fit an 18 month to 2 yr old. For an exact fit please measure your toddlers feet. Care: hand wash in lukewarm water with a mild detergent. Rinse well and air dry. Will come gift wrapped. Made in a smoke free but pet friendly home.
