Are you wearing socks that leave your feet cold and damp, where bacteria thrive and blisters easily form? Or do you choose socks that keep your feet dry and warm, both in summer and winter?
Not everyone realises how important good socks are — especially when it comes to hiking. In fact, your socks are just as important as your hiking boots when it comes to creating a comfortable climate inside your footwear and preventing blisters.

Which hiking socks should you choose?
For hiking and outdoor use, you should choose socks made from wool or synthetic fibres, as cotton tends to retain moisture.
Merino wool is one of the finest natural fibres available, and its properties have made it a popular choice for both base layers and socks. It provides warmth even when damp, helps regulate temperature in warmer conditions, and has a soft texture that doesn’t itch.
Another advantage is its natural odour resistance, which helps reduce unpleasant smells — a major benefit when it comes to socks used over multiple days.
One drawback of wool is that it can lose its shape when wet, which is why it is often blended with synthetic fibres to improve durability and maintain structure.
Regardless of which socks you choose, a general rule for hiking is to use two layers: a liner sock and an outer sock.
What is a liner sock?
A liner sock is a thin inner sock with a close fit, often made from merino wool or synthetic materials.
When worn together with a thicker outer sock, friction occurs between the layers instead of directly against the skin. This helps reduce the risk of blisters.
It’s also important not to wear boots that are too tight, as this can restrict blood circulation in your feet and reduce overall comfort.
How many pairs of hiking socks do you need?
The number of socks you should bring depends on the length of your trip, but it’s generally a good idea to change socks regularly.
For example, you can hang a damp pair on your backpack to dry while you continue hiking.
If possible, rinse your socks along the way so you always have a clean pair ready to use. During breaks, take the opportunity to air out your feet and let them dry.
Dry skin is less vulnerable than damp skin, which helps reduce the risk of blisters and improves overall comfort on the trail.
