Waterproof Flip Flops That Actually Go Everywhere
Right then, imagine a flip flop that doesn't panic when it encounters water. Rather marvellous, that. Our Duckbill women's flip flops are 100 percent waterproof and equally at home splashing about on land or taking a proper dip. They're the sort of shoe that makes you feel rather clever for owning them.
Why Choose Our Duckbill Flip Flops
Grip That Actually Works: Our Gumtread recycled rubber outsoles flex and grip like a tyre, whatever terrain you're foolishly wandering across. Biodegradable jute fibres keep them together year after year, so you won't need to replace them every five minutes like most flip flops.
Straps That Won't Let You Down: The woven recycled PET straps are waterproof, beautifully gentle on skin, and provide non-slip security whether you're at the beach or the dock. Support that doesn't require an engineering degree.
The Clever Textured Top Layer: That rather fetching textured EVA upper directs water and air flow precisely where it needs to go, giving you grip even when everything's thoroughly soaked. Flexible, springy, and absolutely fabulous for water sports on ocean, river, lake, or pool.
Do Something Good: With each pair purchased, one mangrove tree gets planted in Africa through our partnership with local communities. Adventure with a purpose, essentially.

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!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us
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.
