inooknit insoles are made of TENCEL™ Fibers and the bottom is made of Bio PU Foam. It is recommended to hand wash with water or put it in a laundry bag in a low-temperature setting. It is natural for the insole to curl after washing and it will return to flat after drying. Natural fibers can’t avoid balls of fibers after use. It is recommended that the insole be replaced as a condition to maintain wearing comfort.
