US “little kid” size 2. In excellent preworn condition. They do run a bit large. My 7 year old wore them in the size 2 while she wore 3 in Target shoes and vans. Side zip for easy on and off. I do not have the original box. These currently still retail on Zappos so I’d recommend reading reviews to get idea of fit. Dr Martens are so durable this is my third pair. Keep buying bigger sizes cause they are awesome and never show much wear!
