Dr. Martens Juniors 1460 Softy T Leather lace up boots, US 4, UK 3

These Doc Martens kids/juniors boots are in very good used condition- great tread and only a few scuffs on toes. I haven’t tried to wash at all. The only issue is that my daughter took the insole out so she could use her superfeet insoles with them and I cannot find them. Will update listing if I do. Size says US M 4 so I am fairly sure that’s the correct kids size…but it also says US L 5 (see photo of inside stamp.) Either way, UK size is 3 and EU size is 36.
