I love these socks for my 4 year old daughter. For reference, she is wearing size 8.5 shoes. I ordered her size 3-5 years and they fit her well. I love the variety of colors - they're great for fall. They are a comfortable weight, not too fat and not too thin. They went well with her leather boots. I also love the elastic band, it adds subtle detail and classic style to these socks. These socks aren't the softest, as another reviewer pointed out. My daughter is used to wearing wool so these socks don't bother her. If you have a child who is sensitive to textures, this is something to consider. I'm happy with this set of socks, especially for the price.
