Why You'll Love Onyx Thongs

  • Custom-Moulding Comfort: Engineered with a premium EVA foam base that reacts to your body heat and walking gait, dynamically moulding to the unique shape of your foot for custom arch support.

  • Premium Woven Strap: Features a soft, flexible woven strap that sits comfortably against the skin, eliminating friction and providing a secure, breathable fit for all-day wear.

  • Refined Leather Detailing: Upgraded with a stitched leather BURNSEA logo patch on the strap, elevating these from a standard beach flip-flop to a stylish everyday essential.

  • 100% Waterproof & Odour-Resistant: The closed-cell foam structure actively repels water and sweat. They dry instantly, float in the ocean, and naturally resist odour-causing bacteria.

  • Shock-Absorbing Impact: Millions of microscopic air bubbles act as tiny springs beneath your feet, absorbing the harsh impact of concrete and reducing joint fatigue.

  • The Ultimate Everyday Versatility: The sleek, deep black 'Onyx' design pairs effortlessly with everything from boardshorts at the beach to casual weekend wear.

How to Care for Your BURNSEA® Onyx Thongs

Taking care of your thongs ensures the EVA foam continues to provide ultimate custom-moulding comfort and the polyurethane (PU) upper stays looking sharp.

Routine Cleaning

  • The EVA Foam Base: Because our closed-cell foam is 100% waterproof and naturally resists odour, dirt will not soak in. Simply rinse the base under warm water. For stubborn sand or mud, use a soft-bristled brush (like an old toothbrush) and a drop of mild dish soap to gently scrub the footbed and sole.

  • The Polyurethane (PU) Upper: PU is a highly durable, water-resistant material, but it requires a gentler touch than the EVA foam base. Clean the PU surface with a soft, damp cloth. If needed, use a small amount of mild soap. Rinse off any soap residue with a new damp cloth.

  • Drying: Always let your thongs air dry in a shaded, well-ventilated area. They will dry incredibly fast on their own.

What to Avoid (The "Do Nots")

  • Avoid Extreme Heat: Never leave your thongs baking in direct, intense sunlight, inside a hot car, or next to a heater. Extreme heat can cause the EVA foam to shrink or warp, and it can dry out the PU upper, causing it to crack over time.

  • No Washing Machines: Never put your thongs in a washing machine or tumble dryer. The heat and harsh tumbling will damage the bond between the strap and the base.

  • No Harsh Chemicals: Avoid using bleach, alcohol, or heavy-duty household cleaners. These will strip the colour and degrade both the PU material and the foam matrix.

  • No Stiff Brushes on the Upper: While a brush is great for the foam base, using abrasive scrubbers or stiff bristles on the PU upper can scratch and permanently damage the finish.

Long-Term Care Tip

If you are packing your thongs away for the winter, ensure they are completely dry first. Store them in a cool, dry place out of direct sunlight to maintain the integrity of the shock-absorbing air bubbles and the strap's flexibility.

Questions Answered

What is EVA?

EVA (Ethylene-Vinyl Acetate) is a highly versatile, premium foam. Unlike traditional rigid rubber, our EVA foam is "closed-cell," meaning it traps millions of microscopic air bubbles inside the material. These bubbles act as tiny springs to absorb the impact of every step, reducing foot fatigue.

Are they durable?
Can I wear them all day?
Do they come in different sizes?
Are they water-proof?

Yes! The shock-absorbing soles cushion your feet, making them ideal for extended wear.

EVA is universally classified as a closed-cell foam, making it physically impossible for water to permeate the structure. However, the upper material is polyurethane (PU). PU is a highly durable, water-resistant material, but it requires a gentler touch than the EVA midsole and outsole. Wipe the upper with a clean, soft, damp cloth. If necessary, use a tiny amount of mild soap and wipe away any residue with a fresh damp cloth.

Yes, Burnsea Onyx thongs are durable and offer great value. The EVA material is tough and built to last through daily wear.

The Onyx thongs are available in five Australian sizes, ranging from 7 to 11.
