The Only Flip Flops That Actually Work in Water
Look, we'll be honest. Most flip flops are rather useless the moment they get wet. These ones are not. They're 100 percent waterproof, spectacularly grippy, and rather marvellous whether you're paddling about on a lake or simply avoiding puddles on the pavement.
Why Choose Our Duckbill Flip Flops
Gumtread Recycled Rubber Sole: Flexible, durable, and grippier than a platypus's determination. The tyre-like tread means you won't slip about on wet surfaces, slippery rocks, or dock boards.
Waterproof Recycled PET Straps: Woven for genuine support and comfort without the soggy regret. These straps stay put whether you're in the sea or the shower, and they're rather gentle on the skin too.
Textured EVA Upper Layer: This is the clever bit. The bumpy surface directs water away from your foot while providing the sort of grip that actually matters when you're wet. Splendid for water sports, quite the showstopper for everyday wear.
Environmental Impact: Every pair plants one mangrove tree in Africa through our partnership, supporting local communities and protecting habitats for the next generation of adventurers.

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

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.
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.
