An ankle sock is a short, low-cut type of sock that typically covers the foot up to the ankle bone. It is designed to provide comfort and support while being discreetly hidden inside shoes. The ankle sock is often made of breathable materials such as cotton or synthetic blends, offering moisture-wicking properties and preventing odor buildup. With its snug fit and minimalistic design, the ankle sock is a versatile accessory suitable for various activities, from casual wear to athletic pursuits.
