Why are sock liners important?
If you’ve ever been hiking or even just worn shoes before during your life, chances are pretty high that you’ve gotten a blister at least once or twice. The dreaded blister is caused by an excessive amount of friction, which causes your skin to develop a “hot spot” where the heat of the friction starts physically affecting your body.
If left to linger and if continuously exposed to more friction, the hot spot in question can turn into a fluid-filled blister… ew. Even worse, a fluid-filled blister can be so painful that it prevents you from walking, or it can get infected after being exposed to all of the lovely microbes in the wilderness – two things we definitely want to avoid on a hiking trip.
Many proponents of sock liners tout a liner’s ability to reduce friction and help reduce the risk of blistering as one of the main reasons to wear them. However, many people also enjoy sock liners because they can be really effective at wicking away excess sweat and moisture during a hike. Basically, you can think of sock liners as a base layer for your feet!
Do you need sock liners?
Ah, the age-old question: do you actually need sock liners? Well, if you’re a sock liner enthusiast, your answer is probably a resounding “yes!” but many others among us aren’t so sure.
Since many people get on with their hiking life just fine without sock liners, it’d be difficult to argue that you definitely need to get yourself a pair of sock liners. However, if you’re new to hiking or you’ve never even tried sock liners before, it’s definitely worth investing in a pair to try them out.
Because sock liners are fairly effective at wicking away moisture and reducing friction on your feet, they can be a great way to help prevent blisters. Additionally, many people find that their hiking boots actually fit better when they wear sock liners.
Therefore, if you’ve never tried sock liners but are questioning whether or not you actually need them, it’s probably worth investing in a pair just to try them out. You might find that you love them, but worst case scenario, you have a really lightweight pair of socks that you can wear with dress shoes, around the house or when it’s absurdly hot outside. Could be worse.
Do sock liners prevent blisters?
Since very few things in life are certain, we’re going to stay clear of saying that a pair of sock liners will definitely fix your blister issue as we can’t guarantee that they’ll work for your feet. However, due to their ability to wick moisture from your foot and reduce friction, sock liners are pretty effective at reducing blisters when used properly.
If you do get a pair of sock liners and find that they’re not helping to reduce your blister problem, you might also want to take a look at the fit of your boots and how you’re lacing them up. Boots that are too big or too small often will increase your risk for blisters, as will boots that are laced too tightly or too loosely. Sometimes, the boots themselves are the problem as they just seem to rub your feet in the wrong way.
All that being said, blisters can be a great and effective part of a blister mitigation strategy, so they’re worth testing out on your next hike.
Sock liner considerations
Before you jump right in and buy the first pair of sock liners you see, however, there are a few things you ought to know. Here are the most important features to keep an eye out for when buying a pair of liner socks:
Most sock liners are made from materials such as silk, nylon, polyester, or even merino wool. These materials feel great against the skin, breathe well, and dry quickly, which makes them ideal for use as a sock liner.
Like regular socks, you can choose from a variety of different lengths for your sock liners. Probably the most popular sock liner length is the mid-ankle or crew length, as this tends to work best with hiking boots. However, you can opt for low-cut liners if you’re looking for something to wear with your low-top hiking shoes.
Your sock liners should be pretty thin as they’re not really supposed to provide any insulation. Instead, your sock liners should just act as an extra barrier between your foot and your sock, so thinner is usually better when it comes to liner socks. Usually, you’ll want to look for sock liners that are no thicker than a pair of pantyhose or two as anything thicker will just be bulky inside your boots.
One of the main purposes of liner socks is to wick moisture from your feet, so choosing a pair that is made with a moisture-wicking material is pretty important. Merino wool is a naturally great moisture-wicking option that resists that lovely “outdoor smell” while polyester blends tend to wick well, too, at a more affordable price point.
When sizing sock liners, you’ll want to get a pair that’s snug, rather than loose. This is because loose liner socks tend to bunch up at the bottom of your boot, causing the very blisters they’re meant to prevent. Therefore, if you’re in between sizes, you’ll probably be better off by sizing down on your next pair of liner socks.
