Vibrant yellow and blue sneakers with a Velcro closure for easy wear. A must-see for train enthusiasts! These are collaboration shoes with the Shinkansen bullet train: "Dr. YELLOW," "E5 Series," "E6 Series," and "E7 Series," a collection featuring colors and patterns inspired by the four Shinkansen vehicle types. They come in a box with an illustration of train tracks on the lid, making them perfect for gifts. These "IFME" kids' shoes combine various health features with a cute design, designed with children's feet in mind. They focus on "landing," "stability," and "powerful push-off" in three steps. These kids' shoes support smooth weight transfer across the sole. The wide-opening belt and tongue structure makes them easy to put on and take off. 【Windlass Sossa】 (Insoles that help form the arch of the foot): The two indentations at the tip make it easy to bend and stretch the toes, tensing the plantar fascia and naturally training the arch of the foot. 【Outside Strap】 A strap is attached to the outside of the heel for easy on and off. 【Lightweight Sole】 A soft, strong, and lightweight sole that feels like you're barefoot. Thank you for viewing.
