Ashinaka (half-sole sandals) are: ● Stimulating the toes and soles of the feet to promote blood circulation and lymphatic flow, aiding in foot function recovery, and promoting 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 to bed can warm your feet. The correct way to wear Ashinaka 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 first wear Ashinaka cloth sandals correctly, it may be painful or tiring. As you wear them daily, your feet will become stronger, and you will be less likely to get tired even after wearing them for a long time. It is sufficient to start with 5-10 minutes, so gradually get used to them without overdoing it. They can be washed 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. Please note that the color of the actual product may differ slightly from the photos. Thank you for viewing.
