These bright blue hiking socks for men with dark blue and yellow stripes at the top are made from merino wool, which has great moisture-wicking and antimicrobial properties. What does that mean? Basically, you can get away with wearing them a few more times between washes than an ordinary sock, making them ideal for longer getaways on the road or the trail.
