Where are socks marked according to uniform regulations?

Socks in the uniform regulations of the Marine Corps are specifically marked on the top of the foot. This positioning ensures that the marking is visible when the socks are worn, allowing for easy identification and compliance with uniform standards. Placing the marking on the top of the foot helps maintain a neat appearance, as the top of the foot is visible when the Marine is wearing dress shoes or boots. Proper marking also assists in uniform inspections and ensures that all personnel maintain uniformity in their attire, which is a crucial aspect of Marine Corps discipline and presentation.
