The Oakley SI Boot Socks deliver mission-ready operational performance engineered specifically for long hours spent in military, law enforcement, or heavy outdoor boots. They are built from a highly technical, fast-drying synthetic blend that effectively moves moisture away from the skin to help prevent blisters. Integrated mesh vent panels are layered across the top of the foot to maximize airflow, keeping your feet cool and dry under intense physical exertion. Strategic cushioning zones are mapped throughout the footbed to optimize support and eliminate pressure points inside rugged tactical footwear. Finished with an antimicrobial finish to repel odor-causing bacteria, these professional worn olive boot socks are an essential base layer for field utility.
