I love that I found a natural fiber (possibly?) sock. I thought merino! But your description also says cotton. So… merino cotton blend? Works for me. Ordered a navy 2pk and a gray 2pk. They arrived and they looked small. The description says they fit children’s shoe sizes 9-3. My son is a size 13.5 or 1. The navy socks were 2” too short for his foot (the heels were at his arches!) and the grey were about an inch too short (the heels curve was under his heel). We got these for hiking so the fabric felt nice for that. Heavy but breathable. The socks are sturdily made! But the sizing is way off. These might fit toddler feet well, but they are definitely not made to fit children wearing shoe size 9-3. Or 9-13. Perhaps they meant 3-9?? But the package says they fit kids US shoe size 6-8, and I am assuming they mean toddler size 6-8. I’d give them 5 stars for value (if they fit) but I cannot assess comfort as they don’t fit remotely. I’m taking two stars because the description (ss included) is so very wrong when it comes to size. We are returning if possible or donating if not. Great quality socks! But beware the sizing issue!!
