Familiar quality in Converse Mini

We ordered the Converse Chucks 14 months old for our son. I was initially unsure as to Chucks take what size I now generally yes be somewhat larger. Visually they looked also relatively large. He wears normal size 21. Have then decided on the size 5 and they fit like a glove. Had they been too great if we had used in the winter just as slippers. Conclusion: Again and again, Converse Chucks!
