Quick Picks: Hiking Liner Socks

What are Sock Liners?

Sock liners are thin socks that you wear with thicker socks while hiking. These thinner socks have benefits, including sweat-wicking and blister prevention.

Sock liners can work well as a base layer, but you can also wear them on their own. They help keep your feet cool and dry. They can also help prevent blisters.

Sock liners should be thin and fit well. These types of socks are meant to conform tightly to your feet when worn with your hiking boots. 

You can even find sock liners in toe-sock styles for efficient skin coverage, even between your toes.

What Materials are Best for Liner Socks?

Look for moisture-wicking and quick drying materials. Most sock liners are made from wool, nylon or acrylic, polypropylene and/or polyester blends. 

These fabrics are ideal for sweaty feet. They pull moisture away from your feet and redirect it onto your outer pair of socks or your hiking shoes.

This helps keep your feet dry which keeps them cool. It also makes your feet more resistant to blisters.

When your feet are wet from sweat, your skin is softer. Soft, moist skin is more susceptible to blisters than dry feet.

Do Sock Liners Really Work?

Yes, sock liners do really work. Whether you choose to wear them alone or with a thicker pair of socks, sock liners are great for hiking in any weather.

In hot weather, your feet sweat more. Wearing sock liners helps keep your feet dry and cool, even if it seems counter-intuitive.

In cool weather, sock liners have the added benefit of helping to keep your feet warmer. Wet feet are cold feet, and your feet still sweat in cold weather.

Hiking liner socks worn in cold weather pull sweat and moisture away from your skin and also provide an extra layer of insulation for warmth.

Alternatively, you can wear hiking liner socks by themselves in warmer weather. They still have moisture-wicking properties when worn alone.

Instead of directing moisture and sweat to your outer layer of socks, it will go to your shoes instead.

How to Choose Hiking Liner Socks

Since liner socks are meant to be lightweight, moisture wicking and conforming to your feet, there are a few factors to look for in liner socks.

Different liner socks appeal to different people, and we’ve got a great selection of liners in this article.

* Weight: Liner socks should be thin, lightweight socks. Some liner socks can be thicker, but weight ultimately is a matter of personal preference.

* Cushion: Hiking liner socks should not have any cushion. These socks are meant to be worn in tandem with thicker, cushioned socks.

* Length: Sock liners for hiking should be as long or longer than your regular socks. This prevents them from slipping down and causing discomfort.

* Materials: Liners should be made from moisture-wicking and quick drying materials. A liner sock should be comfortable and stay in place without extra bulk.

* Style: Believe it or not, this is an important consideration. If you can’t stand toe socks, you’re not going to enjoy them as toe sock-style liners.

* Durability/Warranty: Since liner socks are usually pretty thin and lightweight, be sure to choose a good brand with a good warranty.

Due to their thin nature, liner socks may wear out faster than regular socks. You still want them to last. Look for brands that offer guarantees on their socks.
