Athletic socks are not just sports socks with a logo. Different activities need different support. If you wear the wrong sock, you will feel it by the end of the day.
For running, look for sports socks with mesh panels and a snug fit. Cushioned socks in the heel and toe reduce impact. Cotton is comfortable, but for heavy sweat, a synthetic blend dries faster.
For the gym, gym socks need to stay put. A little compression in the arch helps. Ankle socks and quarter socks are popular because they do not get in the way.
For work, work socks and men's work socks need to be durable. If you are on your feet all day, thick socks with cushioning can save your knees and back. Crew socks offer more protection than low-cut styles.
There is no single best sock for everything. The best sock is the one that matches the job. Tell us what you are doing, and we will tell you what to wear.
