What is a "crew sock"?

A crew sock is a type of sock that typically comes up to the middle of the calf or just below the knee. It is usually made of a soft, breathable material like cotton or wool and features a ribbed design that helps keep the sock in place without slipping or sliding down. Crew socks are a popular choice for everyday wear and can be worn with a variety of footwear, from sneakers to boots. They also come in a range of colors and designs, making them a versatile addition to any wardrobe.
