When winter arrives, many people reach for the thickest socks they can find.
It makes sense—thicker should mean warmer, right?
Not always.
The truth is that warm feet aren’t simply about adding more material. They’re about choosing the right fibres, the right construction i.e. how the fibres work together (or against each other) when knitted and a sock that manages moisture just as well as it provides insulation.
Whether you’re heading out for a morning run, walking the dog, hiking a trail or simply commuting to work, the right winter socks can make every step more comfortable.
Cold feet are often caused by moisture rather than temperature alone.
Your feet contain thousands of sweat glands and continue producing moisture even on cold days. During exercise or even a brisk walk, that moisture can build up inside your shoes.
If your socks can’t move moisture away from your skin, your feet may begin to feel damp. As you slow down or stop, those damp socks can leave your feet feeling noticeably colder.
That’s why the best winter socks don’t just insulate—they also help keep your feet dry.
There’s a reason Merino wool has become the fibre of choice for runners, hikers and outdoor enthusiasts.
Fine Merino fibres help regulate temperature across a wide range of conditions. They provide warmth on cold mornings while remaining comfortable as your body temperature rises.
Merino is also naturally breathable and helps reduce odour, making it an excellent choice for long days outdoors.
Unlike traditional coarse wool, quality Merino feels soft against the skin and is comfortable enough for all-day wear.
Absolutely. But wool fibres can feel scratchy against the skin, particularly wool used in the cheap and nasty socks. Standard wool is still warm, but the biggest difference is it doesn’t breathe as well, as the fibres are not as fine so don’t wick moisture away from the skin as well. This is why Merino is the choice for outdoor activities. Standard wool is still fine for everyday wear as long as you understand the limitations.
Not necessarily.
Very thick socks can sometimes reduce airflow and, if they make your shoes fit too tightly, may even reduce circulation.
Instead of choosing the thickest sock available, look for one that balances warmth, cushioning and breathability. And of course that will fit in your shoe.
A well-designed medium-weight Merino sock will often outperform a bulky thermal sock because it manages moisture more effectively while still trapping warm air where you need it.
Not all Merino socks are made the same.
When comparing winter socks, look beyond the label and consider how they’re built.
Some of the features worth looking for include:
These details often make a much bigger difference than simply increasing the amount of padding or the percentage of wool.
Winter in Australia is different from many parts of the world.
A morning might begin close to freezing before warming into double-digit temperatures by lunchtime. Your socks need to adapt to those changing conditions.
We’ve been focused on creating Australian-made performance socks (GearSocks), that balance warmth, comfort and durability rather than simply making them thicker.
By combining Australian Merino with carefully selected performance fibres that work seamlessly with each other, we aim to create socks that stay comfortable whether you’re running, walking, working or exploring the outdoors.
Like every GearSocks product, they’re developed through continual testing and feedback from customers because we know there’s always room to improve.
Before buying your next pair, ask yourself:
Choosing the right sock for the activity is often more important than choosing the thickest one.
A good winter sock should do more than simply feel warm when you first put it on.
It should stay comfortable throughout your walk, run or workday by helping regulate temperature, managing moisture and providing lasting support where you need it most.
Whether you’re training through winter, heading into the mountains or simply trying to keep your feet comfortable on cold mornings, choosing quality materials and thoughtful construction can make a noticeable difference.
If you’re looking for Australian-made Merino performance socks designed for local conditions, explore our Winter Collection and find the pair that suits the way you move.
Stay moving,

Hiking in the mountains is amazing. Jagged landscapes, peaceful surrounds, but it can come with challenges. Having the right sock is crucial, especially when trekking at higher altitudes.
Do you actually need a running vest? We look at when they make sense, what to look for, how to get the fit right when buying online, and why rucking vests deserve serious respect. Plus, our ongoing investigation into abandoned gel wrappers.
Stepping off an expedition ship into the dense, humid embrace of Papua New Guinea or remote Indonesia is an unforgettable adventure. Whether you are navigating muddy jungle tracks, exploring remote island villages, or walking hours in tropical heat, your feet bear the absolute brunt of the journey. Recently, we helped a customer preparing for an Indonesian and PNG expedition who faced a unique set of challenges: navigating tropical humidity, wearing lightweight hikers in the jungle, managing crew-length bug protection, and carefully balancing foot health considerations.

If you’ve got cold feet, or worse, chilblains, you probably don’t want to read a 3,000-word review comparing 47 different socks, 19 types of wool and whether a sock performs better at 800 metres above sea level.
You just want your feet to stop freezing. Fair enough. We get customers who contact us and say something along the lines of: “I get chilblains. My feet are always cold. What socks should I buy?”
