Girls' Kids' Shoes - Comfortable and Pain-Free, Perfect for Shichi-Go-San (7-5-3 Festival) - Embroidered, Flat, Easy to Walk In, Japanese-Style Pattern Inner Length: 16.3cm Red I recently purchased these on Mercari and my daughter wore them for about 2 hours during Shichi-Go-San. My 3-year-old daughter usually wears 15.5cm sneakers, but they fit perfectly when she wore slightly thicker kids' tabi socks. I received tabi socks when I rented the kimono, but I didn't use them, so I'm including them as a set. The tabi socks size is 15-16cm. Please purchase only if you understand that these are used items.
