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 conducted at Seoul University. Three secrets born from considering a baby's feet: ・Helps develop the correct walking style! Based on biomechanics, the rounded shape with thickness at the toes was achieved through research on the shape and movement of a baby's foot. The toes and heels provide support, 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. ・Easy to keep clean! One of the pleasing features is the ventilation holes in the sole, which makes it less likely to get stuffy. It can be hand-washed or washed in a washing machine using a "delicate wash" cycle with a laundry net. So, it's always clean and comfortable to use! I have stored these at home, so please refrain from purchasing if you are looking for a perfect item. #FirstShoes
