Awesome Socks! This are now the only socks I buy since I retired and don’t need dress socks Extremely durable, comfortable and versatile. I’ve probably bought over 20 pairs of these socks over the last 5 years and only had issues with 2 pairs. One of them, the toes wore through prematurely and they replaced them for me. Another one the Heel wore through. This just happened and I assume they had some problems with this style because I don’t believe they carry them anymore. All in all they are great quality socks for an active lifestyles of running, hiking and biking.
