These socks are great.
The toe seam on one of the socks came undone after the second washing, so I e-mailed Champion. Within two weeks they had sent an entire new six pack of socks without require I return the defective sock!

I only rate them 4 starts because of this issue, but the other socks in the pack were perfectly fine and I buy Champion brand sport socks for my husband all the time.  They are durable and comfortable.
