This is the 4th order I've placed looking for seamless socks for my 5 year old. They appear to have a seam but when you touch it it's smooth so it's visually misleading and hard to fake my baby. Also, they have long laces at the ends where the thumb and little finger are. They are also a bit big. I plan on washing one of the pairs to see if they shrink, if not. Oh. I will send them back too.
