Do Hiking Sock Liners Prevent Blisters When Hiking Or Backpacking?


We Review The 6 Of The Best Hiking Sock Liners Of 2021

When you are planning a hiking trip, I’m sure you aren’t thinking about what socks you are going to wear. Why do your socks matter? Can’t you wear your favorite pair of athletic socks and call it a day?

While those socks are broken in and probably really comfortable, do they have the ability to protect your feet from wet socks caused by moisture? Did you know that your feet are going to be more likely to blister if your socks are damp?

Blisters are excruciating, especially when you are hiking. What if there was a way to avoid blisters altogether? Lucky for you, that’s where sock liners come in.

What Are Sock Liners?

Hiking sock liners are worn underneath/within the outer sock. Simply put, you have two layers of socks on

Sock liners are designed to be worn underneath another pair of socks (the outer sock) as a back-up to prevent blisters. They are a base layer that keeps your feet dry with moisture-wicking technology.

These liner socks also act as a barrier for friction, ultimately reducing the possibility of a blister occurring. Also, these hiking socks are breathable and comfortable.

Typically, these liners are made from materials such as a thin polyester, light wool, and others. These synthetic materials work very well when it comes to comfort in any weather.

Besides separate sock liners, you can also get a liner explicitly made for the trail runners, boots or shoes you wear hiking. It can be attached to your shoe entirely, or you can have it be removable so you can wash it. They are great for adding extra comfort, and keeping your feet warm or cool.

Can Sock Liners Really Help Prevent Blisters?

Yes, they can significantly reduce your chances of getting a blister from your hiking boots. Because these socks are designed to help wick moisture away from your feet, they will stay dry all day long. They also act as a barrier layer, meaning you will experience less friction between your feet and your boots.

They are also useful because they work as a second layer. Instead of just one layer, two layers can further prevent any friction you may experience from your boots. Instead of rubbing against your foot, like with one layer, two layers rub against each other.

What To Look for in a Sock Liner?

Sock liners may be essential if you get blisters when you day hike. But what exactly do you need to be looking for? There are several factors you should think about when looking for your perfect sock liners.

Sock Seam Location/Seamless

For the best comfort from your liners, you will want to get a sock with a flat seam on the toe. This will be less annoying than a thick seam.

You may even want to find a pair of seamless liners; that way, you won’t have to worry about an uncomfortable seam at all.

Sock Padding/Thickness

Sock liners are not specifically designed to add any additional support to your feet. It is not every day that you will find liners that have padding, but it is not impossible. However, if you want padding, your boots might fit tighter, making your day hike uncomfortable.

Sock Material/Breathability

Sock liners are usually made from synthetic materials because they are the most efficient at wicking away moisture and sweat from your feet. Wool socks keep your feet warm in the winter and cool in the summer. This makes wool ideal for any type of weather.

Other popular materials are polyester, silk, and nylon. These materials reduce friction from your feet rubbing against your boots.

Sock Length/Durability

The length of the liners you choose are pretty much up to your preference. You can get a higher sock if you have high-top boots. However, the most common length is crew.

Crew length is the most popular because it doesn’t have a bunch of excess material that can bunch up, and they are long enough to adjust them how you want.

Sock Thickness

When you are looking for a sock liner, you want to make sure it is thin. They are designed to be worn underneath other socks, so the thinner, the better. You will also want to make sure that you get a thin pair to fit in your current pair of shoes.

FAQs

How/Why Do Blisters Form When Hiking

Blisters form when your boots rub against your skin for an extended period of time, like when you are doing a lot of walking on a hike. Blisters are also formed when your feet are covered in water or sweat.

What Kind of Socks Prevents Blisters?

Sock liners are very efficient at preventing blisters for several reasons. The first reason is that they add a layer of protection between your skin and your boot. You may need to invest in a high-quality pair if you hike frequently and want to prevent blisters on your foot from your boot.

What Should I Do if a Blister Forms Even with a Liner?

If you continue to get blisters, even with sock liners, you will need to cover the areas you get them most often. You can do this in several ways, but the best is using a liquid bandage.

Some other ways to cover your blister areas are moleskin and tape. Stick tape directly to the places where you notice the most blistering, like the back of your heels. This will reduce friction to the bare minimum, lowering any chances of a blister forming.

You could also try to lubricate with deodorant or Vaseline before putting your liners on. This will act as another protective layer and prevent as much friction as possible. It would help if you reapplied any lubrication after walking about 10 miles for the best results.

How Necessary Are Sock Liners, Really?

Sock liners are necessary to help prevent blistering on your foot if you are prone to them. They are also important because they help keep your foot comfortable in any weather situation. They can help keep your foot warm in the cold and cool in the heat. They are necessary because they work, and they will keep you blister-free, especially on your longest hiking trip. You won’t regret adding a liner to your boots.
