These thongs are soft, yet very supportive with a unique design that separates Aussiana thongs from all other flat styled thongs on the market. They feature a recessed heel to assist in holding your foot in place while walking, a raised arch to support the met and arch area of your foot and a tarsal bar under your toes to relieve the need to clench your toes to hold on to the thong as you walk. They also feature hundreds of oval shaped massage nubs to stimulate circulation from your feet up by pushing inwards with every step, you will be pumping blood and relieving pain in your legs from long periods of walking or standing.
