Calling the SealSkinz Hiking Mid Sock just another sock is like calling Nepal's trek to Everest's base camp just another trail. This sock sports a waterproof, breathable membrane similar to ski shells, so you can rest assure your foot will stay comfortably dry as you hike through the incremental climates found throughout the Tour Du Mont Blanc. SealSkinz lined the sock in merino wool for natural odor-resistance and midweight thermal regulation that warms your foot up when it's cold and vice versa. SealSkinz also padded the heel, toe, and footbed to absorb shock and reduce blistering on long hikes.
