The Champion C-463 is a medium duty controlled 
      stretch ankle support that can be worn for mild
      sprains and strains, or for weakness due to previous
      injury or over-exertion. It provides a comfortable
      uniform compression over the affected area while helping 
      to permit continued activity and preventing re-injury. 
      Two flexible stays on each side enhance stability
      without affecting normal movement
      Open heel prevents irritation and binding, allows support
      to fit easily into shoes
