Pointing out hazards for the guy behind you, I feel like this is not done by most people. Can be done with either a leg or a hand, and is greatly appreciated by those of us who break the following too close rule.
Darn Tough Mountaineering Over the Calf Sock. I've worn these in the military, hiking all day as a wildland fire fighter, on duty as a police officer, mx racing, track days, and now adventure riding. I've had the same 8 pairs since 2008, these are hands down the best made socks I have ever owned!! I've used these in +110 and -30 weather, they wick sweat, stay cushioned, and dry out super fast. And.........and....... life time guarantee!! Which I have never had to use. Just my 2 cents.
