If you struggle with blisters or uncomfortably sweaty feet, liner socks could be the solution for you! Sock liners are a great line of defense against moisture that can cause blisters or discomfort. Keep reading for our tips on using liner socks and our suggested styles that will keep your feet cool and comfortable.
What is a liner sock?
Liner socks are a thinner type of sock that are usually made of material that encourages moisture to be wicked away from the skin. They work much like any base layer garment does by wicking sweat up to the next layer of clothing. So, usually, you use a liner sock underneath a thicker “outer” sock; the lightweight, moisture-wicking liner will draw the moisture away from the foot and pass it to the outer sock where the moisture can evaporate. By reducing the amount of moisture against your skin, you are less likely to have uncomfortable rubbing, which can lead to blisters.
Sock liners are usually made of thin polyester, nylon, lightweight wool, or other natural or synthetic fiber blends that help wick sweat away from your feet. Wool sock liners are one of the most popular liners because wool fibers are known for their temperature regulating properties. So wool sock liners can keep your feet cool in the summer and warm in the winter! While wool is great for regulating temperature, other fibers can be more breathable and quick drying. For example, polyester is quick drying, while nylon is lightweight, strong and can absorb more moisture than other fibers.
No matter which material the liner sock is made of, you’ll always want one that is as thin as possible. The thinner the liner sock, the more comfortable it will be to wear under your outer sock. Contrary to what you may be used to looking for in other outer socks, remember you won’t be sacrificing any performance by getting a thin liner sock. Liner socks are meant to be thin!
When should you use a liner sock?
Regardless of the time of year, a liner sock is sure to wick away moisture, dry fast, and have great anti-blister qualities. This is why some people in warmer climates use liner socks as their go-to lightweight style! While liner socks are designed to be worn underneath an outer sock, their amazing cooling capabilities make them a great performance sock option all on their own.
However, the real purpose behind liner socks is to reduce blisters when your outer sock is intended for other things, like keeping your feet warm. Liner socks are popular options for cold-weather sports like hockey, snowboarding, and skiing. Because those activities generally require the outer layer to be warm and protective against snowy conditions, adding a liner sock underneath can be great for wicking away sweat and reducing the chance of blisters. Plus, an added benefit is that liner socks help to keep your outer socks in place when you can’t reach down to fix them during these types of high-intensity activities.
Liners are also great for hiking and backpacking treks when you can’t always be sure what the weather will be like. By applying the tried-and-true concept of layering to your feet, you increase the range of comfortable temperatures. You’ll also reduce the chance of rubbing from your hiking boots, which will help to reduce blisters.
