This 6PK of Allsport, Low Cut Socks from PowerSox (which is a Gildan company) was well received by my boys - even the ones with wide feet.

The fiber content is 80% cotton, 17% polyester, 2% nylon, and 1% spandex so they don't shrink or stretch out of shape with wear. They are just a bit thicker than ordinary, white socks and feature a grey heel and toe, which is nice since those areas seem to get grungy really quickly. They hit just below the ankle bone on my boys and are comfortable even for my son who wears a size 13 shoe. (Not big enough for my son who wears a size 15, though.)

Good, serviceable socks at a good price. I'm happy.
