Sock liners are an essential piece of kit to help protect you from blisters. We have all had the nightmare of breaking in new shoes or out hiking or enjoying a leisurely walk…only to find ourselves having to hobble the rest of the way home – the best sock liners are the solution to this problem.
Blisters are caused when your skin encounters an excessive amount of friction, and this causes a ‘hot spot’ to develop on the skin – this occurs when the heat from the friction starts to physically impact the body. If left unattended, you end up with a fluid-filled blister, which, apart from being painful, increases your risk of infection. This is especially an issue if you plan to hike out in nature; the wild is full of nasty germs just waiting for a chance to clamber into a warm environment. (See here for the best hiking socks)

Can Sock Liners Really Help Prevent Blisters?
The best sock liners are designed to help reduce this friction, thereby reducing the likelihood of a blister forming in the first place. In addition, they can be useful for removing any excess moisture or sweat which may build up during your hike, and act as a valuable protective base layer for your feet.
If you are brand new to the world of hiking or are in the process of breaking in a new pair of boots, sock liners could prove to be your salvation. If you have never tried them before, there is absolutely no harm in giving them a go; they are affordable, lightweight, and could totally transform your hiking experience for the better.
One of the biggest endorsements for sock liners is that they can help to reduce the likelihood of you developing painful blisters, but is this really the case? As with anything in life, there are no guarantees, but certain features of sock liners do help to reduce the likelihood of you developing painful and unpleasant lesions.
Because sock liners work to wick moisture away from the feet, they can really help to reduce the friction which is a common cause of blisters. Liner socks also add extra padding and protection, so in the event that your boots do rub, there will be an extra layer between them and your skin, and this reduces the chances of you developing a blister, or allowing the boot to rub directly at delicate skin.
Sock Liners Buying Guide
If you do decide to go down the route of finding the Best Sock Liners, there are a few key factors to consider which will help to ensure that you make the right choice.
The most popular liner socks are made from high-quality materials that focus on breathability, and these include merino wool, silk, polyester or nylon. All of these materials help the skin to breathe properly and feel comfortable to wear. They also dry quickly, and this means they are a top choice for use in sock liners.
Length of the Socks
Just as with non-hiking socks, there is a range of lengths to choose from. Mid-ankle and crew length are the most popular choice, and these go well with hiking boots. Low-cut options are also available if your boots are cut at a lower or medium level.
Sock liners are not intended to provide insulation, and so tend to be fairly thin. They act as an additional barrier of protection, and so are rarely thicker than a pair of pantyhose. If the weather is bad, you will need an extra pair of cold weather socks for warmth, and so the last thing you need is a bulky pair of liners clogging up your boots.
A key advantage to liners is their ability to wick the moisture from your feet. Merino wool, Smartwool and polyester are great materials for this and can help to reduce the unpleasant smell which can come with sweaty or damp feet.

When it comes to sock liners, size matters. It is better to choose a pair which are a little too snug, rather than opting for a looser size up. If your socks are too loose and baggy, there may be extra material which bunches at the bottom of the boot, and this can result in a one-way ticket to some pretty bad blisters; the exact enemy which your liner is trying to prevent! Make sure that your choice is snug and comfortable; not too tight to cause discomfort, but not so large that they have any excess.
Budget is perhaps the first consideration; the amount you have to spend will impact the selection which is available to you. Quality sock liners are available at a range of prices, so don’t be put off by the high prices of the top-end choices. If you are just trying out sock liners to see if they suit you, it may be a good idea to pick up a cheaper pair at the lower end of the budget. If you get on with them, you can look at investing slightly more money in a higher-end pair, and if not, there is very little lost!
Investing in a great pair of sock liners can really make a difference to your overall comfort, and massively improve the quality of your hike, run or outdoor activity. Out top pick has to be the Outdoor Obsession sock liner; it is sturdy, flexible and designed to keep moisture well away from your skin. Even better, they are super comfortable, and will enhance any trek, rather than weighing you down!
I love hiking. From the Camino de Santiago to the West Highland Way in Scotland or simply a great day hike on the weekend. Hiking refreshes me, my mind, and keeps my body reasonably fit. So far I have walked three Camino routes and many other long distance hikes in the UK, Canada, and around the rest of Europe. One of the best was my hike up Ben Nevis.
