Port is a comfy slide sandal. Naot's removable, anatomic cork & latex footbed is wrapped in leather & microfiber and molds to the shape of the foot with wear. The removable footbed is held in place with hook & loop strips. The Vineyard Collection features a 2" polyurethane sole which is extremely lightweight and durable. This collection has a metal shank built into the sole for extra stability. Our patented Naot Replacement Footbeds are also available for Port.
