The U.S. Postal Service gives these Thorlos Over the Calf postal socks a stamp of approval., featuring lightweight padding in the arch and midweight padding at the ball and heel to protect against impact, shock, blisters, and abrasions.
The Navy Postal Socks' flat knit instep is perfect for a better fit and moisture evaporation. Acrylic keeps feet drier on the inside, while the reinforcing nylon is knit to the outside of the sock providing outstanding durability and great comfort and protection while on the job. The postal socks are navy with postal blue stripes.
