Hi everyone,
Every time I walk onto the track or into a clubhouse to coach, I witness the same pattern. Athletes rocking carbon-plated super-shoes worth half a week’s rent, wearing watches that claim to know their VO₂ max better than their own lungs, and recovery gadgets that look like they were stolen from NASA.
And then… they peel off their shoes and reveal socks that look like they were part of a school uniform pack from 2009.
Cotton. Mid‑calf. Faded. The kind of sock that has seen things.
Each to their own I suppose - and whether you buy from us is not the point - but I do believe they are leaving some performance on the table.
Let me put this in perspective.
Most runners don’t realise how much time they lose from sock weight alone.
A standard cotton sock weighs around 70-80 grams per pair, while a high‑performance pair sits under 40 grams. That’s a 30‑gram saving before you even start moving.
Multiply that by the 42,000–45,000 steps in a marathon and you’re lifting an extra 1.3 tonnes (cumulative) of sock weight over the race.
Research shows that every 100 grams added to footwear increases oxygen cost by around 1%, which means your old socks are quietly taxing your running economy by 0.5–1.0%. It doesn’t sound like much, but over a marathon, that’s worth 45–90 seconds of free speed — before you even factor in blister prevention, moisture control, and gait stability.
Shoe companies shave grams for a reason. It works. And your socks are the easiest weight savings you’ll ever make.
Even if the benefit is mostly psychological, there’s a real “I’m dialled in” feeling that comes from knowing every part of your setup is intentional. When an athlete ignores the one piece of gear that touches their skin every millisecond of a race, they’re basically saying their comfort and stability are “good enough.”
In sport, “good enough” is the enemy of a PB.
If you want to explore how different socks affect performance, you can check out our Run Socks Collection once you’ve read through this.
Years ago, when Andy Murray came to Australia for the Open, he didn’t leave his sock choice to chance. He sourced his specific performance tennis socks — from us. Because when you’re sprinting, sliding, and changing direction like a caffeinated border collie, you don’t want to think about your feet. You want to think about your serve.
If one of the world’s best athletes is that meticulous about a $30 pair of socks, it’s worth asking yourself: why aren’t you?
Let’s pull back the curtain on the most boring piece of gear in your setup — and why it’s secretly one of the most important.
The Comfort–Performance Paradox: Softness Is a Scam
Cheap socks are designed for one thing: feeling soft in the shop.
Cotton is the ultimate con artist. It feels great when it’s dry… and then your foot starts sweating like it’s trying to win a competition. Cotton absorbs that moisture, holds onto it, and transforms into a heavy, abrasive, friction‑creating swamp rag.
Wet sock = friction
Friction = heat
Heat = blisters
Blisters = you limping through your run like you’ve been tranquilised
High-performance socks don’t chase softness. They chase mechanical integrity — staying dry, holding shape, and keeping your foot locked in place.
If you want to compare materials, you can explore our Materials Lab where we break down Merino, bamboo, Meryl Skinlife, and our synthetics.
Your foot is a tiny tropical rainforest. It dumps heat and moisture constantly, and your sock is the climate control system.
Cheap socks trap heat, turning your shoe into a steam room. Not to mention the smell. Technical fibres — Merino, bamboo, performance fibres — wick moisture, regulate temperature, and prevent the swelling that makes your shoes feel like they’ve shrunk mid-run. Oh and they minimise and/or elminate stinky feet.
If you want a deeper dive into moisture management, temperature regulation and blisters you can read more in our ProLab Blister Prevention Guide.
If I could remove one thing from an athlete’s life, it would be the blister. A blister is your body saying:
“You’ve created too much friction and I’m tapping out.”
To prevent this, you need:
• Moisture-wicking fibers
• Structural tension that keeps the sock in place
• Seamless toe seam construction so you’re not fighting a toe seam at kilometre ten.
Cheap socks bunch. Bunching creates folds. Folds create pressure. Pressure creates blisters. Blisters create sadness.
If blisters have been sabotaging your training, our Blister Prevention Hub breaks down the mechanics behind skin shear, moisture, and sock movement.
Just like shoes, your socks should match your training phase.
Base Phase: High Volume, High Density
Wear socks with targeted cushioning — like our Glide Bamboo — to protect your fat pads and reduce impact stress.
You can explore Glide Bamboo in our Training Socks Section.
Switch to ultralight racing socks. No dead weight. No soggy fabric. Just pure responsiveness.
You’ll find these in our Racing Socks Section.
Match your sock density to your workload. Your feet will thank you. Your PB will thank you. Your physio will thank you.
If you invest in technical socks, treat them like technical socks.
• Avoid high heat — tumble dryers kill elastane
• Use gentle detergents — protect Merino and synthetics
• Wash inside-out — remove sweat and skin buildup
If you cook your socks in a dryer, they will come out looking like they’ve aged 40 years overnight.
• The Material Check — Merino, Bamboo, High Performance Synthetics
• The Elasticity Test — must snap back instantly
• The Target Zones — density where you strike, mesh where you sweat
You can explore all of these in our Run Socks Collection.
I’ve coached athletes from their teens into their masters careers. The ones still running strong at 40, 50, 60, and 70 are the ones who respected their feet. They didn’t settle for “whatever was in the drawer.”
Your feet are the most sophisticated piece of machinery you own. Treat them like it.
If you’re tired of blisters, bunched-up fabric, swamp-foot humidity, and socks that feel “dead” after three washes, it’s time to upgrade.

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.
