Your New Favourite Excuse to Leave the House (or Stay In)
Rather like a well-meaning but endearingly scruffy Australian wild horse, the Brumby slipper boot refuses to be confined. It's indoor comfort with outdoor credentials, channelling that intrepid spirit into something you'll actually want to wear from the sofa to the garden shed and, if you're feeling adventurous, considerably further afield.
Why Choose Our Brumby Boot
Durable Outdoor Soles: Our signature Gumtread outsoles are flexibly tough and gloriously grippy, taking you from fireside lounging to après-ski wandering without so much as a wobble. Built from recycled rubber, so every step rather loves the earth back.
Recycled PET Felt Uppers: Wonderfully soft and vegan-friendly, our recycled felt provides that cosy sensation without any woolly guilt. Second-life materials that look and feel utterly fetching.
Plant-Based Comfort: Foam insoles crafted from organic plant-derived materials mean your feet get properly looked after, and the planet does too.
Elastic-Sided Versatility: Inspired by Australian work boots, the Brumby slides on and off with marvellous ease. Perfect for gardeners, campers, wanderers, skiers, and anyone who'd rather not stand still but prefers to do so in comfort.
Ocean-Positive Impact: Each pair recovers the equivalent of 80 plastic bottles worth of ocean and riverbank plastics through our partnership with local waste-pickers across South-East Asia and Africa. Harmful plastic pollution transformed into the soft felt that keeps your feet cosy.

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.

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.
