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, durable and provide a tyre-like grip for whatever terrain you might encounter. Biodegradable jute fibres reinforce and preserve the integrity of the rubber, so the adventure keeps on going year after year. COTTON SOFT - finishing touches matter. That's why we use soft cotton canvas for both our toe posts and strap linings. We want your feet to feel as comfortable as possible, which is why we've added a thin layer of the same recycled cotton canvas to the footbed.
