Keeping your feet warm as if by magic (but more like a double layered design with a fleece lining), our SOCKSHOP Harry Potter Chunky Cable Lined Slipper Socks are thick and comfortingly cosy. Knitted from heavy gauge yarn in Gryffindor house colours, the socks have a deep cable rib pattern, which would be warm enough on its own, but allied to a soft Sherpa fleece lining, they are certain to keep you toasty, even in the winter scenes of Harry Potter and the Goblet of Fire.These Harry Potter slipper socks are non-elasticated, so they are completely comfy for all-day lounging at home and wont constrict anyones legs or ankles. They include sticky silicone anti-slip grip dots on the soles for safety around the ancient polished wood and stone of school halls or your own lovely laminate home floor surfaces. Underlining the Harry Potter theme, the socks include a patch of the Hogwarts School badge affixed to each leg.
