Review on PJ Masks Character Socks Small by Elder Unogu

The sock size chart on this product shows that XS is for 2-4T shoes and size is 4-7. My 18 month old is 90% smaller for his age and already wears a size 7 shoes. I understand he has big feet but I took the size XS because it fits 2-4 year olds and his socks are barely there now fit. From "standard size" to "shoe size" is correct, but be careful when specifying the age. I don't think 4 year olds wear size 7 shoes. For reference, I also have a 4 year old who wears size 10 shoes. According to the sock size chart they published, children aged 4 to 6 wear size 7 to 10 shoes. The socks themselves are ok
