Jacks Waterproof EVA Sandal - NavyThe signature Jacks Flat Sandal is comfortable from the beginning, without needing break in time. The new footbed and outsole design has been created with improved flexibility and traction for comfort. The upper design is slotted into the footbed, providing a better hold that will ultimately mold to your foot, creating your own exclusive and personal pair. We also redesigned the toe post for a more natural and comfortable fit.
