Baby Feet Love-Red 12.5cm Materials: Upper: Cotton, Polyurethane Sole: Thermoplastic Rubber These "training shoes" are more convenient than regular shoes and were created for babies taking their first steps, based on the biomechanics research of Seoul University. Three secrets born from considering a baby's feet: ・Develops the correct walking style! Based on biomechanics, the shape is rounded with thickness at the toes, the result of research into the shape and movement of a baby's foot. Power is applied to the toes and heel, firmly protecting the soles of the feet, and allowing comfortable walking without slipping on flooring. *Uses lightweight and soft thermoplastic rubber. Therefore, you can walk correctly and smoothly, more so than with shoes, bare feet, or socks! ・Safe materials! Thermoplastic rubber (TPR) is a material also used in baby pacifiers. There are no seams, and no adhesive is used, so it's safe for babies. Also, no harmful substances are released when burned. Therefore, it's a very gentle and safe material for both people and the environment. ・Keeps them clean! The soles have ventilation holes, making them less likely to get stuffy, which is also a nice feature. They can be hand-washed or washed in a washing machine using a "delicate wash" cycle with a laundry net. So you can always keep them clean and use them comfortably! I have stored these at home, so Please refrain from purchasing if you are looking for a perfect item. #FirstShoes
