Rather Good Slipper Boots That Actually Work Outdoors
Look, we rather like these. They're the sort of thing you put on and immediately wonder why you didn't own them sooner. Part slipper, part outdoor boot, entirely splendid for anyone tired of choosing between comfort and actually leaving the house.
Why Choose Our Slipper Boots
Exceptionally Versatile Comfort: These manage the rather impressive feat of keeping your feet warm all year round. Winter by the fire, summer on the patio, those awkward shoulder-season mornings when you can't quite decide what season it is. They adapt beautifully.
Sustainably Made Materials: We've crafted these from recycled PET felt uppers (wonderfully soft, thoroughly vegan-friendly), plant-derived foam insoles, and recycled rubber outsoles. Nothing flashy about it, just honestly made.
Gumtread Outsoles That Actually Grip: Our signature high-grip soles are flexible and durable, designed for everything from fireside lounging to back garden wandering. They won't let you down on slippery surfaces, and they're made from recycled rubber because every step should count.
A Touch of Understated Distinction: These aren't your ordinary slippers. They're rather fetching in grey and curry, the sort of thing that looks properly thoughtful without trying too hard.

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.
