All socks are not created equal. These U.S. Military Surplus X-Static Cushion Sole Socks are 3 steps ahead of most socks you'll find in a retail store. For starters, the fabric blend is carefully curated for long-wearing durability, comfort, moisture management and odor control. Strategically placed padding helps prevent blisters and minimize abrasion. Plus, spandex helps keep them from slouching. It all works together to provide performance the U.S. Army relies upon year-round to keep America's soldiers comfortable and highly motivated.
