These Merino-Possum Baby Heart Socks are knitted in New Zealand by one of our oldest and most experienced knitwear manufacturers Norsewear. These socks are made from a blend of 40% Merino wool, 30% Possum fur, 10% Silk, 18% Nylon and 2% Lycra. Nylon and Lycra are necessary to ensure that the socks are sturdy and durable. They are substantial thick socks knitted with a looped terry stitch on the inside for comfort and warmth. They are guaranteed to keep little feet cosy and warm whether they are worn with or without shoes. Made in three practical colours these socks are long lasting and come in three sizes to fit from a new baby to a four year old child. These socks should be washed in cool water using a liquid detergent but they should not be tumble dried.
