Here’s a question we get almost every day:
“What’s the best running sock?”
It’s a fair question.
After all, runners will happily spend $350-$450 on the latest carbon-plated shoes, analyse their cadence, obsess over VO₂ max and debate the merits of one energy gel over another…
…then head out wearing the oldest pair of cotton socks they found at the bottom of the drawer.
It’s a little like buying a Ferrari and fitting it with bargain tyres. Sure, it’ll still move—but you’re not getting the best from it.
Your shoes do most of the work. Your socks make sure your feet can actually enjoy it.
As a running coach, I’ve seen it countless times. Great fitness. Great shoes. Poor sock choice. Then come the blisters, hot spots, numb toes and sore feet.
Now, before someone jumps into the comments saying, “I’ve run for 20 years in cheap cotton socks and never had a problem,” you’re probably telling the truth.
Some runners can get away with almost anything. Some can eat a meat pie before a marathon, never stretch, ignore recovery and still run well. Good luck to them.
We’ve all done things that worked despite being terrible ideas. Eating a family-sized pizza the night before a race. Running in brand-new shoes. Thinking, “She’ll be right,” after spotting a black toenail.
Sometimes you get away with it.
Sometimes you don’t.
Sock choice is much the same. Plenty of runners have completed marathons in ordinary socks. That doesn’t mean ordinary socks are the best tool for the job. It just means they were fortunate enough not to find their limit that day.
The goal isn’t to find the cheapest sock that might work. It’s to choose the sock that stacks the odds in your favour—reducing friction, managing moisture and helping your feet stay comfortable from the first kilometre to the finish line.
The good news?
Choosing the right running socks isn’t complicated once you know what matters.
If you’re comparing different styles, it’s worth browsing our Running Socks collection first. Seeing the different materials, cushioning levels and sock heights will make the rest of this guide much easier to understand.
Let’s start with the biggest mistake.
Let’s clear this up straight away.
Cotton isn’t evil.
It’s fantastic for lounging around the house, watching Netflix or wearing to work.
Running?
Not so much. Cotton absorbs sweat and hangs onto it. Instead of moving moisture away from your skin, it becomes damp and stays damp. Add thousands of running strides and you’ve created the perfect environment for friction.
And friction’s favourite hobby is making blisters.
If blisters regularly cut your runs short, it’s worth reading our guide to Blister Prevention Socks. Often the right sock—not just the right shoe—makes the biggest difference.
Instead, choose technical running socks made from fibres like Merino wool, Coolmax®, bamboo blends or performance synthetics that are designed to help manage moisture and keep your feet comfortable.
Your feet shouldn’t feel like they’re marinating by kilometre five.
Some runners think thicker socks are for “soft” runners.
They’re wrong.
Every step while running places significant force through your feet. Over a marathon, that’s tens of thousands of impacts. Good cushioning helps spread that pressure more evenly across your foot and can improve comfort over longer distances.
And here’s another reality…
The older we get, the less forgiving our feet become.
At 18 you could probably run across a gravel carpark without thinking twice.
At 40?
You sleep in the wrong position and need a recovery day. There’s no prize for uncomfortable feet.
If cushioning is your thing Thorlo Socks use high-density cushioning to absorb impact without feeling bulky, making them equally comfortable during everyday training, long runs and race day.
Choose the cushioning that matches your training—not your ego.
You wouldn’t wear a puffer jacket in the middle of summer.
Your socks deserve the same consideration.
Hot Conditions
When temperatures climb, look for lightweight running socks that breathe well and move moisture away from your skin.
Less moisture generally means less friction.
Cold Conditions
Merino wool is hard to beat.
It keeps your feet comfortable across a wide range of temperatures, continues to insulate when damp and naturally resists odours remarkably well.
Winter running suddenly becomes much more enjoyable when your toes still work afterwards. If you mainly run through the cooler months, check out our Merino Running Socks to see why they’ve become a favourite among distance runners.
A quality running sock is far more than a tube of fabric.
Here are the features worth looking for.
Arch Support
A supportive band through the middle of the foot helps keep the sock secure and reduces movement inside your shoe.
Ventilation Zones
Mesh panels improve airflow where your feet generate the most heat.
Think of them as air conditioning for your feet. Not quite as exciting as carbon plates—but arguably more useful after 20 kilometres.
Seam-Free Toe Construction
Notice we didn’t say “seamless.” There’s a good reason for that.
Despite what marketing sometimes suggests, virtually all knitted socks have a seam somewhere. The important part is that the toe seam is smooth and comfortable enough that you don’t notice it during your run.
If you’ve ever wondered why, read our article on The Seamless Sock Myth where we separate clever marketing from how socks are actually made.
Deep Heel Pocket
A well-shaped heel helps stop the sock sliding around inside your shoe. Because once your sock starts moving, blisters usually aren’t far behind.
This surprises a lot of runners.
Changing socks can completely change how your shoes feel. A heavily cushioned sock reduces the available space inside your shoe.
That’s fine—unless your shoes already fit snugly. On longer runs your feet naturally swell. Add a thick sock into an already tight shoe and you may end up with pressure points, numb toes or that annoying feeling that your shoes suddenly became half a size too small.
Many runners keep a lighter sock for racing and faster sessions while using more cushioned socks for everyday training and recovery runs. Learn about ‘The Ferrari Effect’ to help you run better.
Your feet will tell you what they prefer. Listen to them.
Technical socks aren’t difficult to care for. But plenty of people unknowingly shorten their lifespan.
A few simple tips:
Think of it this way.
You wouldn’t drive your car 50,000 kilometres without rotating the tyres.
Your running socks appreciate the same courtesy.
Not every run needs the same sock.
Marathon Training
Look for comfortable cushioning that helps manage long hours on your feet.
Speed Sessions
A lighter sock gives a closer connection to the shoe and often feels faster and more responsive.
Trail Running
Trail running socks often include extra protection around high-wear areas while offering excellent durability for rougher terrain.
Tree roots have an uncanny ability to appear exactly where you’re planning to land. If your weekends are more mud than pavement, take a look at our range of Trail Running Socks designed for rough Australian conditions.
Toe socks definitely divide opinion.
Some runners love them. Others look at them and wonder whether their feet have suddenly developed fingers.
By separating each toe, toe socks can reduce skin-on-skin rubbing, making them popular with runners who regularly suffer blisters between their toes.
They’re not essential.
But if blisters are ruining your runs because your toes rub together, they’re certainly worth trying.
We explore the pros, cons and surprising benefits in our guide to Toe Socks.
Sometimes the socks that look the funniest solve the most frustrating problems.
Compression socks have become increasingly popular with runners.
Some athletes wear them while running. Others prefer them afterwards. Current research suggests they may help reduce the feeling of muscle soreness and support recovery for some people, although results vary between individuals.
If you finish a long run with heavy, tired legs, they may be worth adding to your recovery toolkit.
Worst case?
Your calves look extremely athletic while you’re making coffee.
We all have them.
The socks that have seen every PB.
Every race. Every muddy trail. Every washing machine known to mankind.
But eventually even the best running socks wear out.
Cushioning compresses. Elastic stretches. Fabric becomes thinner.
If your socks are slipping, bunching or developing thin spots, they’ve earned a well-deserved retirement.
Thank them for their service. Then buy another pair.
The honest answer?
The one that suits your feet, your shoes and your running.
There isn’t one perfect running sock for everyone.
Some runners love maximum cushioning. Others prefer lightweight performance.
Some swear by Merino wool. Others won’t run in anything except toe socks.
The key is finding the combination that keeps your feet comfortable from the first kilometre to the finish line.
And here’s something we’ve learned after years of fitting runners…
The best running socks are the ones you never think about.
Let’s face it—they’re socks.
They’re never going to be as exciting as a new pair of running shoes, a flashy GPS watch or crossing the finish line with a new PB.
Their job isn’t to steal the spotlight.
Their job is to quietly disappear.
No rubbing. No slipping.
No blisters. No hot spots. No numb toes.
You put them on before your run… and somewhere around the first kilometre you completely forget they’re even there.
That’s exactly what great running socks are supposed to do.
Because when your run is over, you should be thinking about your pace, the scenery, the coffee afterwards or the finish line—not your feet.
After all…
Great running socks don’t demand attention.
They quietly earn it.

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.
“What’s the best sock to wear?”
It’s one of the questions we’re asked almost every week.
Whether it’s in our inbox, on Facebook running groups, at race expos or through social media, the questions are remarkably similar.
“What’s the best marathon sock?”
When we talk about running socks, "comfort" is the number one criteria. If a sock doesn't feel right, it’s going to end up buried in the back of your sock drawer after one use. But there’s a massive difference between "cozy" comfort and "performance" comfort.
We recently received a great question from a customer planning a high-altitude expedition. He’s heading up to 6,400m and was looking for advice on how to avoid foot issues during the long trek, as well as how to manage his gear for that final summit push.
