I know you want to buy a pair of cute infant shoes, before he gets here. A size 0 will probably be best for now, be sure they are infant shoes and are soft soled. He won’t be walking, or crawling, so no need for “real” shoes just yet. Another way they size them is “newborn” or “nb,” “0 3,” “3 6” etc. They may also go Air Jordan 6s by single numbers, like 1, 2, etc. You will want a 1. I think my daughter was in a 3 or 4 Air Jordan 12s at Air Jordan 6 Rings 6 months, maybe? I don’t remember exactly. But the smallest Air Jordan 11s size will probably work for a baby under 8 lbs, and maybe the next size for a bigger baby. My dd was 9 lbs! Also, like the other poster said, he prob won’t wear them much, but I understand you wanting to buy some!This Internet site provides Air Jordan 9s information of a general nature and is designed for educational purposes only.
