ONYX - Sandale Noir

🌊 Turning ocean waste into sandals
Nuo sandals start where most products end. Discarded flip-flops recovered from the ocean are cleaned, shredded and pressed into our colourful signature soles. Instead of creating new materials, we give existing ones a second life.

🌱 100% Vegan
No leather. No animal glues. No compromises. Our sandals are entirely cruelty-free because fashion shouldn’t cost animal lives. For us, that’s not a feature, it’s the baseline.

👣 Made to move with you
From beach days to city streets, our sandals are built for everyday wear. Cushioned and durable, designed to look bold and feel comfortable wherever you go.

♻️ Lower impact, by design
Each pair rescues around 300g of ocean flip-flop waste. We prioritise recycled materials, minimise virgin plastics and assemble everything responsibly in Spain under strict EU standards.

• 300g of ocean waste flip-flops rescued per pair - iconic colourful midsole
• Vegan & cruelty-free materials
• Extra-soft cushioned footbed
• Made responsibly in Spain
• Unisex

Upper: Recycled PVC with a leather-look finish. PVC is a durable, flexible type of plastic. Ours is recycled, giving it a second life instead of ending up as waste. Treated to look and feel like leather, minus the animals.

Inner: Soft-touch textile lining that keeps your feet feeling good, even after hours.

Midsole: Our signature colourful nuoceans layer, made from 100% recycled flip-flops pulled from the ocean.

Footbed: 100% recycled cork with a 3mm cushioned foam layer on top. Cork is a natural, sustainable wonder - it’s insulating, shock-absorbing, and harvested from the bark of cork oak trees, and in our case, reused from cork waste like wine stoppers etc.

Outsole: Recycled EVA - lightweight, springy, and amazing at softening every step. EVA (ethylene vinyl acetate) is an elastic material with excellent cushioning, so every step feels softer. And, in our case, it’s made from leftover EVA scraps from the shoe industry, saving perfectly good material from going to waste.

2-3 working days (depending on location, it may take up to 4 days).

Currently we ship to Austria, Belgium, France, Germany, Netherlands, Spain and the UK.

Upper: Clean away dirt using a damp cloth only. Allow to dry, then clean with a soft dry sponge. Do not use leather cleaner as this may damage the finish.

Insole: Use baking soda & a bit of water to create a paste. Rub onto the footbed and leave to set for an hour. Clean with a damp or dry sponge. Removes dirt, sweat and odour.

We do not recommend this product for use in water. Prolonged exposure to water can damage the product.
