PLEASE NOTE: THE 3.3 IS A DIFFRENT FIT TO THE CLASSIC THEY HAVE A HIGHER ARCH. Having a pair of thongs is an Australian tradition. They just make life easier! But for some people who need extra orthotic support and comfort, they are always out of reach. Specifically designed for the everyday aussie with orthopedic needs, these thong’s have anatomically correct arch support, a heel cup, and a tarsal bar, so your foot is snugger than Snugglepot and Cuddlepie! Even better, every pair of Starfish Orthotic Thongs is made out of vegan friendly single injection construction, which means no plugs! REVIEWS: Starfish Classic 3.3 Arch Support ThongsI love Aussie Soles, these starfish classic 3.3 style seem to be a little wider fit than the starfish arch support style which fit my narrow feet a little better. Much kinder to my very flat feet that many other jandals. Starfish Classic 3.3 Arch Support ThongsLove these contoured snug fit thongs. I have been wearing these for a few years now and am loving the new arch support I recently purchased.
