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 small sox is 102 cm x 69 cm and would fit an average 3 - 5 year old. It is essential that a therapist recommends this item for the user before purchasing.
