Theses socks are so comfortable perfect size and thickness theses were the only socks I took on a 2 week Ireland trip with me. These are a great value for your money and they look so cute on, I could not find any socks in Ireland that were as soft and have the durability that these have. I highly recommend! I am a sock lover also and picket about texture.
