Derek D.wrote a review of Injinji Liner Crew CoolMax Sock - Men's on February 6, 2017
Familiarity: I've used it several times
Fit: True to size
I use these under darn tough socks for hiking. I've used them several times so far on short hikes(5 to 10 miles). They definitely add comfort as far as temperature control and friction. My feet feel fresh throughout the hike, and feel really cool after taking off the wool socks with these still on. I am considering buying more so I can layer for work- maybe I won't be thinking about getting home to get my work boots off throughout the day!
