These socks earn their title of Endurance. I took them to Fort Polk, LA for a training rotation at JRTC. I wore them for 48 hours straight without taking them off.
I had no blisters. No hotspots. The socks didn’t fall below my boot opening.
I was carrying 100+ pounds of weight for over 2 miles in the cold, dark, and wet for about 8 hours.
Couldn’t ask for a better sock.
