The Slipper That Actually Goes Places
Right, so we've rather mucked about trying to make a slipper that doesn't immediately fall apart the moment you venture beyond the front door. Turns out we've succeeded. The Outback is that rare thing: a slipper with genuine ambition. It'll take you from your living room to the garden, the patio, or wherever life's little adventures call, without forcing you to sacrifice comfort or pretend you're wearing something you're not.
Why Choose Our Outback Slipper
Properly Durable Outdoor Soles: Our signature high-grip Gumtread outsoles are flexible, long-lasting, and gloriously unafraid of rough terrain. Whether you're heading to the fireside or tackling some après-ski wandering, these soles grip like they mean business. Better still, they're made with recycled rubber, so every step actually does something rather good for the planet.
Honest Materials That Feel Right: The felt uppers are crafted from recycled plastic, the foam insoles spring from plant-derived organic materials, and the outsoles come from recycled rubber. Nothing here is pretending to be something it isn't. It's all genuinely sustainable, which is marvellous.
Comfort That Doesn't Fuss: Double-layer felt uppers in a vegan-friendly alternative to wool mean these slip on effortlessly and feel rather fabulous once you're wearing them. No awkward breaking-in period, no cold feet, no nonsense.
Feel Good, Do Genuine Good: Here's the rather splendid bit. With every purchase, the equivalent of 80 plastic bottles worth of ocean and riverbank plastics gets recovered and converted into renewable materials. Some of those materials become the felt in your new slippers. Meanwhile, income flows to local waste-pickers across South-East Asia and Africa. You're not just buying a slipper; you're quietly improving someone's life.

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

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.
