The Best Liner Socks for Hiking

Sock liners are your top defense against sweaty feet and blisters. Typically worn under normal hiking socks, the best styles help regulate your body temperature to prevent sweat from forming, while also wicking away moisture to keep blisters at bay in all sorts of weather.

While some styles vary for use in different climates, they often feature materials like lycra for flexibility and merino wool to help stave off odor-causing bacteria. When hiking in warm temperatures, you may also want to consider an option made of polyester for added cooling effects.

Below, we’ve rounded up some of the best sock liners to add to your hiking wardrobe now. Read on to shop them all.

1. Bridgedale Ultralight Coolmax Liner Socks

Made with merino wool and CoolMax fiber, these socks are designed to keep feet ultra-dry in any weather.

Pros: In addition to helping wick away moisture, merino wool is soft and naturally antimicrobial to help prevent bad odors from forming. Meanwhile, Coolmax helps draw moisture away from the skin and feels smooth to the touch. The socks, which also feature a sturdy thermal yarn that can stand up to multiple washings, are tough enough to be worn on their own if temperatures rise or you need your other socks to dry. They're available in a speckled blue and all-white version depending on your preference. Plus, they come as a two-pack to help you get more bang for you buck.

Cons: These socks tend to run large.

Pros:  The Thermolite polyester material is super breathable and lightweight, so it won't weigh feet down. The socks also come with a flat toe seam to help prevent blisters and uncomfortable rubbing while you hike.

Cons: It's advised to hand-wash these so they don't lose their shape.
