Ashihan (half-foot sandals) are: ● Stimulating the toes and soles of the feet to promote blood circulation and lymphatic flow, aiding in foot function recovery, beautiful legs, and dieting. Effective for improving cold sensitivity and preventing bunions and flat feet. ● Said to improve body alignment and posture. ● Simply wearing them while sleeping can warm your feet. The correct way to wear Ashihan cloth sandals is to have the toes and heels touch the ground. Insert your foot deeply so that your toes extend significantly from the thong, and place your heel on the floor. When you wear Ashihan cloth sandals correctly, it may initially cause pain or fatigue. With daily wear, your feet will become stronger, and you'll find it easier to wear them for longer periods. Start with 5-10 minutes at first, and gradually get used to them without overdoing it. You can wash them in a washing machine using a laundry net. I have included the size, but since they are sandals, you can wear them regardless of size.
