Actual size: Approximately 11 cm x 8.5 cm (Suitable size: Approximately 22-24.5 cm) Made with PP rope. Base and thong are 100% cotton. The thong uses cotton padding. ★ The front part of the thong can be adjusted. If it's tight, adjust it to the perfect length for your foot. ★ The front part uses cotton fabric, so it won't stretch because it doesn't use knit fabric. ★ Reinforced slightly to stimulate the arch of the foot. Wearing Ashinaka (half-foot sandals) allows you to use your toes and strengthens the muscles of your feet. ☆ Gripping the thong opens your toes and prevents bunions. ☆ Stimulates the arch of the foot, improving blood circulation. ☆ Placing your heel on the ground shifts your center of gravity backward, allowing you to stand with a straight posture. ☆ Improves posture and can alleviate lower back pain. Various problems can be expected to be resolved, such as the above. If it gets dirty, you can wash it in the washing machine in a laundry net, but it may fade, so wash it separately at first. When shipping, it will be delivered in a compressed state, so please shape it before use. Pattern/Design...Print (logo, etc.) Material...Cotton
