Great thin-ness, with wise, slight reinforcement at toes and heel
The Wrightsock ultra thin quarter has been my favorite running sock for some time. I have gotten more into trail running, in part to increase my outdoor running during winter, and found I like the warmth in winter, and protection from bugs and plant life in summer as provided by the crew. I have not worn crew or higher running socks for many years but since I got these, they are my new favorite sock for off road running. The ultra thin is one of the few truly thin socks out there so if you are a thin sock person, this is the sock for you, whether crew or another height.
These are the most perfect socks. They stay up without digging in to the calf. Nice and thin like I like my socks.
