The Lisa is a spectator inspired, toe-post sandal that features a new slimmer footbed for improved midfoot fitting and control. 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.
