Developed with a passion for outdoor life now and for the future, Gumbies™ Islander Flip-Flops provide the freedom of minimalistic footwear while ultimately protecting the sole. Go further, in the Islander. DURABLE OUTER SOLE - our Gumtread™ recycled rubber outsoles are flexible and durable and provide a tyre-like grip for any terrain you encounter. Biodegradable jute fibres reinforce and preserve the integrity of the rubber, so the adventure keeps going year after year. COTTON SOFT - finishing touches matter. That's why we use soft, recycled cotton canvas for the toe posts and strap linings. To ensure your feet experience maximum comfort, we incorporate a thin layer of the same fabric onto the footbed.
