These cotton-rich socks have been approved by the Institute of Chiropodists and Podiatrists and are perfect for those who need to take extra care of their feet. They were originally designed especially for wear by those with diabetes, and are knitted from a breathable blend of 94% cotton and 6% nylon. These socks encourage air flow around the foot, which results in a reduction of moisture, and skin that can breathe freely. HJ Hall's Diabetic socks also feature an easy fit top to ensure there is no tightness around the wearer's ankles, and a smooth toe seam to minimise friction.These socks are also designed for full-day, every-day wear. Not only are they machine washable, but also have a built-in biocidal ingredient called 'ACTIFRESH' which prevents the growth of bacteria using natural Silver ions, and keeps your feet feeling good all day long.
