Sock Geek Says:

Bridgedale's Trail Sport is great for all day trail running, particularly on warm and hot days.  Cool arch venting maximizes air flow.  Use of premium Merino Wool and polypropylene fibers, Endurofil, gives the enhanced sock durability, efficient moisture management, and comfort.  Cushioning under heel with a little more protection in the ball of foot and toes areas.
