This fantastic update to the original features narrower straps and an improved pattern for better toe and midfoot fitting. Invented by leading Australian podiatrist Phillip Vasyli and endorsed by famed Oprah physician Andrew Weil, the sandal features the built-in, lightweight biomechanical Orthaheel footbed that supports your feet while helping to realign the lower legs and improve posture. Made with a durable rubber outsole with wave-patterned tread that helps improve traction on hard or wet surfaces.
