Where are socks marked according to Marine Corps regulations?

Socks in the Marine Corps are marked on the top of the foot. This positioning allows for easy identification and ensures that the socks can be arranged properly, maintaining uniformity and discipline in appearance. When socks are marked on the top, they can be easily read when the service member is wearing them, facilitating quick checks for compliance with regulations. This marking is part of the broader standards of uniformity that are emphasized in the Marine Corps, ensuring that all service members present a professional and synchronized appearance.
