Ashinaka (half-sole) cloth sandals Size: Approximately 8.5 x 12 cm By inserting the thong up to the base of the toes and wearing them with the toes and heels touching the floor, it is said that the arch of the foot is aligned and blood flow improves. Even when sitting in a chair, your feet relax from the toes, and you can expect effects such as relaxation of the mind and body, and the alleviation and prevention of foot problems such as hallux valgus. It is very warm when used in combination with tabi socks in the cold season. Wearing them to bed warms your feet, and we recommend them to those who have cold feet or difficulty sleeping due to tension. If the stimulation is strong, please get used to wearing them gradually, starting with a short time until your feet get used to them. If the thong is tight or the front part has stretched, you can adjust it by untying the knot on the back and retying it to fit. You can wash them in a washing machine using a laundry net, but please avoid tumble drying. We appreciate your understanding of handmade products. #HalluxValgus #RelaxationGoods #FootAcupressure #BloodCirculation #ColdFeet #WarmUp #Acupressure #Sleep #ForSleeping #GoodSleep #LowerBackPain #PostureCorrection #CoreStrength #HealthyFeet
