Importance of Tennis Socks
If your feet wear out, so will your game!
I would highly recommend getting the Thorlo Level 3 brand socks, which rarely go on sale and offer the best amount of cushioning (more than the Level 2 and Level 1 socks). I've been wearing these for as long as I can remember because they do a terrific job of preventing blisters (toes and heel have extra padding). The fabric does a great job of keeping my feet cool and dry even in the toughest match conditions.

These socks usually sell for $13+, so getting them at this price probably will not last long. I stock up on these, every time I see them on sale! Amazon has them in many different sizes and styles.
Thorlo's Tennis Sock Design
With just one layer of Thorlo's Level 3 sock, it is equivalent of wearing 2 pairs of other socks together (which some pros will do). Thorlos always wick away moisture from your feet, and these are specifically designed for tennis movements. You can see in the toes and heel areas, they are re-enforced with slightly more padding as these points typically absorb more shock than the rest of the feet.
Different Thickness and Lengths
They typically come in 3 lengths (Crew, Mini, and Micro). The Mini's cover your ankles, while the Micros do not. I own all three lengths but typically prefer the Micro length in the summer. Tip: it is a good idea to alternate between them in order to prevent a solid sock tan from building up around your ankles.
When you wash your Thorlo's socks, it is recommended that you flip them inside-out before putting them in the washer as it helps make the sock last longer.
