These are the circulation-enhancing thermal slippers that provide relief for achy, stiff, and tired feet. The slippers help ease pain caused by sport injuries, arthritis, plantar fasciitis, repetitive strain, and other foot conditions. Three therapeutic layers promote improved blood flow, decreasing inflammation, soothing muscle and tendon discomfort, and warming chilly toes. A soft inner layer wicks away moisture. The middle layer captures your body’s natural skin temperature for heat therapy. The outer layer provides light compression to aid circulation. Flat seams relieve pressure points for sensitive feet. Rubberized anti-slip rubber sole and pull-up tabs. Made of nylon, spandex, rubber, foam, and polyester. Black with gray accents. Imported. Unisex sizes S, M, L, and XL.
