This product is approximately 12cm x 8cm. It is suitable for those who wear shoe sizes 22cm to 25cm (slight variations are acceptable). Ashinaka Zori are zori that were worn for about 800 years, from the Kamakura period to around the post-war era, and are about half the size of regular zori, reaching only the middle of the foot. I made these after working as a chiropractor and reflexologist for 22 years. ☆ Wear them with your heel firmly on the back and your toes extending beyond the zori. ◎ Wearing Ashinaka is said to improve posture by placing weight firmly on your toes and heels, and to train your lower body muscles and core. ◎ The protrusions on the back stimulate the arch of your foot, which is said to regulate autonomic nerve function and provide a relaxing effect. * Refer to "The Key Point" in the first image. ◎ For first-time users, it will likely be quite painful, but please do not give up. Start with short periods and gradually increase the duration. ◎ My husband, who loves foot massages, uses them all the time. ◎ They are washable, so you can use them hygienically. (Please be careful of color transfer) ◎ Please use them indoors only. There have been reports of even better effects when used during sleep. ◎ We ask for your understanding that these are handmade items. ⭐️ Even if the protrusions become flattened, the Ashinaka effect will not be lost. If the thong becomes loose, please retie it from the back or replace it and continue to wear them until they are worn out. * We apologize, but we are currently not accepting new orders. If you like them, please purchase them from here. #ClothZori #IndoorShoes #Slippers #Diet #Ashinaka #FootMiddle #Swelling #Stretching #Posture #BeautifulLegs #Core #FootMassage #HealthSandals Pattern/Design: Floral
