X-Socks Evo Run Sock
Here's what other sites are saying:
X-Socks invests nearly as much in its sock design as NASA does on your average intergalactic mapping project. And it shows in the X-Socks Evo Running Sock. An inner and outer sock layer assist in moisture wicking and minimize abrasion and blistering. AirFlow channel systems woven into the sock keep feet from overheating, and an X-Cross band supports and stabilizes the ankle area. Cushioning at the toes and instep reduce pressure on these areas, and an Achilles Tendon Protector eliminates blister-causing friction at the heel.
