Performance Socks That Actually Work
Rather splendid news: these aren't your standard sports socks. Infused with infrared technology, they're engineered to boost blood circulation, accelerate recovery, and help you push harder without the lingering ache afterwards. Rather like having a personal physiotherapist living in your sock drawer, only significantly less awkward at dinner parties.
Why Choose Our Infrared Crew Socks
- Infrared Technology: Increases tissue oxygenation by up to 20 percent whilst promoting cellular repair. Think of it as waking up your muscles from their afternoon nap.
- Cushioned Comfort: Reinforced heel and toe cushioning with arch support band keeps your feet genuinely happy, whether you're running, cycling, hiking, or simply pretending to exercise.
- Recovery Support: Accelerates lactic acid breakdown and reduces delayed onset muscle soreness. You'll feel less like a creaky gate the morning after.
- Temperature Regulation: Stores thermal energy 63 percent longer than standard fabrics and dries 65 percent faster. Rather clever, that.
- Injury Prevention: 80 percent average reduction in soft tissue injuries through muscle priming. Prevention being rather more sensible than cure, we've heard.
- Antimicrobial and SPF35 plus: Keeps feet fresher and protected. No unpleasant surprises lurking about.

SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
PAYMENT

Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay

We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
