It is vital to keep your cast and dressing dry. Our cast socks are specifically designed for assisting your recovery using the highest quality of Merino Wool - arguably the world's best natural wool fibre. Its inherent properties make the cast sock very warm, breathable, moisture repellent and anti-static. Merino Wool has the capacity to deal with moisture like no other fabric, absorbing perspiration and releasing it into the air as vapour. The fineness of its fibres make it soft and extremely comfortable to wear.
