The Slipper Boot That Actually Makes You Want to Leave the House
Look, we've all pretended our slippers were sophisticated enough for a quick trip to the shops. The Ossa High rather changes that equation. Named after a proper mountain and built with the sort of rugged durability you'd expect from actual hiking boots, these are slipper boots that won't embarrass you when the delivery driver arrives. Plush faux fur lining delivers genuine warmth and softness, while the flexible high-grip outsoles mean you can wander from kitchen to garden without that awkward shuffle most slippers demand.
Why Choose Our Slipper Boot?
Outsoles That Actually Work: Our signature Gumtread technology grips properly, whether you're padding across laminate or venturing onto damp decking. Made from recycled rubber, they're long-lasting and rather kind to the planet.
Comfort Engineered Thoughtfully: The high-top design rolls down or stays snug depending on your preference. Recycled PET felt uppers provide genuine cosiness without the traditional wool, and happen to be entirely vegan-friendly.
Built for a Second Life: Felt uppers from recycled plastic, foam insoles derived from plant-based materials, and outsoles crafted from recycled rubber. Every component has been given a second purpose, which is rather marvellous when you think about it.
Do Some Good While You're at It: Each pair purchased recovers approximately 80 plastic bottles worth of waste from ocean shorelines and riverbanks through our partnership with local waste-pickers across South-East Asia and Africa. Those materials don't just disappear; they become the felt that keeps your feet warm.
Product Details:
Style: High-top slipper boot in navy and pink, versatile enough for indoor lounging or garden wandering.
Upper Material: Recycled PET felt with plush faux fur lining.
Insole Technology: Plant-derived organic foam for lasting comfort.
Outsole: Recycled rubber with high-grip Gumtread traction.
Design: Rollable collar for adjustable fit and snugness.
These are the sort of boots you'll actually reach for, day after day. Rather fetching, properly functional, and they won't judge you for wearing them to answer the door.
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.
