My first grader has become extremely sensitive to the seams of her socks and how they felt in and out of shoes.  We have had many teary mornings and finally gave up on socks altogether.  I was happy to find these "seamless" socks online as I didn't see anything in the local stores.  When she first put them on she noticed the seams and I was a little worried, but she walked around in them, then put on shoes and wore them for the entire day without complaint!  My only complaint is that they are very long--I thought they could be folded over, like a bobby sock, but without folding they reach my daughter's knees, like knee socks.  However, the fact that they are comfortable to her is more important and I'm so happy I just bought a 6 pack of the sport quarter socks.  I would recommend these to all delicate desert flowers with sensitive toes!
