My son wears a size 7 shoe, and according to Gold Toe Boys' Ultra Tec Back Stripe, the plus size three stripes fit a boy's (large) sizes 3-9. Having tried different sock sets for boys and girls from Gold Toe I would say that their products are generally very well made with good combed cotton and well finished stitching however their products tend to run small and the ankle straps/ Rubber bands are too tight. According to my son, these dress socks look more fashionable and thinner than regular cotton crew socks). I think if you want a large (3 gold stripes) you should only buy them for the smallest sizes from the range offered.
