Soft and Warm ★ 2-Piece Set Unisex Fleece Ankle Warmers Black & Arm Warmers There is almost no muscle around the ankles, but nerves and blood vessels run just under the skin, making them susceptible to external stimuli. There are many acupressure points around the ankles, and warming them improves blood circulation. These are soft to the touch and have warm fleece lining. They are a stretchy, free size, so they can be used by both men and women. Perfect for relaxing at home or sleeping, but not too thick, so you can wear them when you go out. They are compact and easy to carry, and can also be used as arm warmers. Basic black, plain. Size/Capacity: Unisex Free Size Ankle Warmers (approx. 22cm length when laid flat) Polyester, Polyurethane Made in China Color: Black Package may be subject to change.
