If you don't have wool socks in your drawer, you should. Hincapie makes it easy with the Edge LT Merino Sock. This Merino wool blend foot covering is temperature regulating and wicking and looks great on the bike and off. The LT is for light to distinguish this as a four season sock. The blend is simply because wool on its own doesn't hold up as well as it does when it's blended. The blend makes wearing more comfortable, thanks to the nylon adding durability and the elastic improving fit. The nylon also makes it easier to wash, while still keeping the temperature controlling, anti microbial and anti stink properties that everyone loves in soft, itch free Merino. The Hincapie Edge LT Merino sock has a five inch cuff. It is mesh on the top, solid on the bottom, and has a hidden seam at the toe. The color is Graphite. Sizes run from Small through X Large.
