Step Outside in Splendid Comfort
Right, so we've rather gone overboard making a slipper that actually works beyond your living room. The Outback does precisely what it promises: it takes you from the sofa to the garden gate and beyond, without sacrificing comfort or looking like you've given up on life. Marvellous, really.
Why Choose Our Outback Slipper
Durable Outdoor Soles Our signature high-grip Gumtread outsoles are flexibly designed to handle everything from fireside lounging to après-ski expeditions. Built from recycled rubber, they're proper hard-wearing and rather kind to the planet with each step.
Recycled Materials Throughout The felt uppers are crafted from recycled plastic, the foam insoles from plant-derived organic materials, and the outsoles from recycled rubber. Every component has been given a second life, which feels rather splendid when you think about it.
Gorgeously Soft and Vegan-Friendly Double-layer felt uppers provide the sort of comfort that makes you wonder why you ever left home. These are made from a vegan-friendly alternative to wool, so your feet stay utterly cosy without any ethical quandaries.
Feel Good, Do Good Each pair helps recover the equivalent of 80 plastic bottles from ocean shorelines and riverbanks. Your purchase also supports local waste-pickers in South-East Asia and Africa, converting harmful plastic pollution into the renewable materials that make your slippers so gloriously comfortable.

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
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!

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.
