These are sneakers from Reima, a Finnish children's clothing brand. Reima is a bit pricey, but I often bought their products because they are highly functional and easy to use. Unfortunately, their online shop in Japan is temporarily closed, making these difficult to obtain currently. In the sixth photo, the same type of shoes are sold on the overseas official website for €49.95 (approximately 8,600 yen as of November 20, 2024). --- 【Color】Green Size 26 US9.5 Approx. 16cm When placing the foot on the sole, it seems the toes should reach the inner line of the sole for the correct size. The inner line is about 15.5cm. My daughters also wore these when their feet were around 15.5cm. The size is just a guide, but I hope it helps. --- My twin daughters loved these because they were easy to wear, but they've outgrown them, so I'm selling them. There are some stains that couldn't be removed by washing at home, but there's little damage, and they can still be worn. According to reviews, they are easy to wear, and some people used them as indoor shoes.
