Four Running Sock Features

When shopping for running shoes, make sure you try on shoes with the socks you're going to be running in because some socks will require you to go up a half-size.

Double Layers
Some runners choose to wear double-layer socks for additional blister protection. These socks are designed with inner and outer socks that are connected—providing an air layer in between to help with wicking moisture away from the foot.

Varied Thickness
Another great feature is padded soles, which can give your heels some extra cushion. Although some runners like thicker socks for additional cushioning, others prefer thin socks for a lighter feel, especially in warmer weather. Other things to look for are a seam-free toe section, which can further reduce your risk of blisters.

Different Heights
Running socks come in various heights, from no-show to knee-highs. If you prefer no-show socks, just make sure that they have a tab that goes above your running shoe and over your Achilles, so your shoe isn’t digging into or irritating your skin.

Compression
Compression running socks or compression sleeves have become popular with runners. These socks have a very snug fit and may take longer to put on. Some are even made out of medical-grade materials. They are designed to help return blood flow uphill to your heart. Compression socks are often used for post-run recovery, and while some runners wear them during workouts, you should get adjusted to using them regularly before committing to them for a long run.
