My husband has to wear compression socks. He had some major swelling for a summer they thought this would help reduce his swelling. He only had to use it for a week and it helped reduce the blood that pooled in his legs after a vein surgery. Still in great working condition I would recommend for any person who needs to reduce swelling in their lower legs use this device to gently Help the blood move out of the lower legs. Can be used for either right or left foot
