The ABAND Ankle Band is a tool that corrects body alignment and maximizes your body's natural functions, just by wearing it. Approximately 70% of Japanese people are said to have flat feet, which was the inspiration for developing the Ankle Band. Simply wearing it on both feet stabilizes your center of gravity, front to back and side to side, and supports beautiful posture. That's the Ankle Band. 【Product Overview】 ・For both feet ・Color: Black (semi-transparent) ・Size: S (21-23.5cm) ・Flat feet / Posture correction / Ankle support ・Recommended for sports, daily walking, and standing work ・Thin design allows for use while wearing shoes 【Shipping Method】 Carefully packaged and shipped via anonymous delivery.
