Designed to be the ultimate trail running sock. The Trail 19 has additional terry padding around the Achilles heel area to eliminate rubbing and blisters. Trail 19 is light wool sock with just enough toe padding to minimize the impact from rocks and roots, without squeezing the toes in the shoe.
Shape You's Review:
The terry padding around the back of the ankle is one of kind. No way a blister is making it through this padding.
