The footbed is contoured with cork-latex for extra support and the inside is lined with suede for extra comfort. An EVA sole is flexible and lightweight, and the sandals feature two adjustable straps with metal pin buckles. The deep heel cup cradles the heel and the longitudinal and transverse arch support help keep your feet in proper alignment. A raised toe bar encourages natural gripping motion and the roomy toe box allows toes to move more naturally.
