The most underutilized men’s accessory today is the least expensive yet trendy item: socks! Most people don’t give much thought to this little accessory, unless one is lost in the wash. There are several types of socks for different occasions and different materials. They include knee socks, crew socks, ankle socks, no-show socks/sock liners, and moisture wicking socks.

These socks can differ in their feel and height.

To help you with your shopping, we’re breaking down the features of these different sock types:

1. Knee socks
These socks, as the name implies, fit up to just below the kneecap. They are typically worn by both men and women beneath slacks, jeans or pants. They offer the most coverage and warmth, especially when they are made with natural fabric such as wool or cotton. They are a good choice to wear under boots because of their higher height.

2. Crew socks 
These socks cover the top of the ankle and are shorter in height compared to knee socks. Men and women wear these socks with shorts, often with a sneaker or athletic shoe. They are often sported by women with casual shorts or skirts, too. They can be made with natural materials or synthetic fibers depending on the need. Cotton socks absorb perspiration while synthetic fibers l allow for stretch and easy care. These sporty socks often has extra padding on the balls of the foot and heel, as well as a stretchable band of fabric over the top of the foot. These features add comfort and flexibility.

3. Ankle socks 
These socks sit just below the ankle bone when worn. They are often sported with athletic shoes and casual shoes when a low coverage sock is needed. They can be made with natural materials or synthetic fibers, such as nylon or spandex. These socks do not warm the feet due to their lack of coverage, but are worn to hide the socks and protect the shoes.

4. No-show socks and sock liners
These socks fit just below the shoe outline, hiding the fact that you’re even wearing them. They protect the wearer from having direct contact with the inside of the shoe, which keeps the feet and shoes clean. It’s a good alternative to higher length socks, especially in a fashion shoe. Sock liners are similar, but essentially just cover the toes and around the bottom of the foot with a heel. Often these two types of socks will have rubber on the inside heel to help keep them in place.

5. Moisture wicking 
These socks are made with a man-made material that absorbs perspiration. The moisture wicking effect is ideal for sports and allows for more comfort. Many hikers, bikers, and recreational athletes prefer these socks to standard material socks. These socks can come in a variety of heights and are easy to care for.
