The Body Sox is specifically designed for spatial awareness and interaction. Each Sox is made from a translucent Lycra with a reinforced hook and loop-closed entrance. Once inside, users find themselves in a space that lures them into kinaesthetic exploration. They begin to understand and explore the 3-dimensional space they individually occupy. Body Sox users quickly find out how easily it is to transform space and how balance and coordination affect this transformation. This x-small sox is 86 cm x 69 cm and would fit an average 3 year old. It is essential that a therapist recommends this item for the user before purchasing.
