socks from Mario at LDComfort. He has them in tall boot length and in shorter, more like a normal sock length.
They're the best sock I've worn for riding, I wear them with Sidi boots and they stop the chafing of the boot on my legs that exists if I'm not wearing a pair of his LDComfort tights.
I also wear the shorter version at work with a pair of Eco boots, they also work great, keep the feet dry and comfortable.
He also offers an inmate discount, find him in the Vendors area.
His LDComfort underwear is the best thing since sliced bread to wear under your riding gear too.
one life, do what you should...
