Actimove Arthritis Care Ankle Support Features:

Joint Warmers
These elastic supports provide light compression for comfortable support. Ideal for arthritis, weak or aching knees, overuse or repetitive use injuries and mild strains.

The Joint Warmers contain unique ceramic fibers that retain heat and slowly reflect it back into the joint and surrounding tissues. The result is soothing relief and therapeutic heat penetrated deep into the aching joint, muscles and surrounding tissues.
