Right then. Imagine a slipper boot so spectacularly comfortable you might never leave home again. The Ossa High is rather marvellous at that sort of thing. Named after a proper mountain, it's built for people who rather enjoy both adventure and the occasional bout of staying indoors with their feet toasty warm. The plush faux fur lining is, if we're being honest, rather fabulous.

Why Choose Our Ossa High Slipper Boot

Splendid Grip That Actually Works: Our signature Gumtread outsoles are utterly fetching and genuinely clever, designed to grip floors brilliantly whether you're padding about the house or venturing outdoors. Made from recycled rubber, they're flexible, long-lasting, and leave a lighter footprint. Quite the showstopper for something you slip on.

Second Life Materials Done Properly: The felt uppers are crafted from recycled plastic, the foam insoles from plant-derived organic materials, and the outsoles from recycled rubber. Every step is genuinely a step in the right direction, if you'll pardon the sentiment.

Your Sole Deserves Better: The clever high-top design rolls down or stays snug and upright, depending on your preference. The super-soft recycled PET felt is a gorgeously vegan-friendly alternative to traditional wool, beautifully made and surprisingly durable.

Feel Good, Do Good: Here's where it gets rather special. With each pair purchased, the equivalent of 80 plastic bottles worth of ocean and riverbank plastics are recovered through our partnership efforts. This harmful waste is converted into the renewable materials that make these cosy felt uppers. Plus, it provides proper income to local waste-pickers in South-East Asia and Africa.

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

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.
