Abstract: A novel footwear construction for sandals including a foot bed, an outsole unit and an adjustable continuous strap for retaining the sandal on a foot. This sandal construction includes an adjustable continuous strap that passes below the user's foot and foot bed and secures the users foot to the top of the foot bed. A reinforcement layer is attached to the bottom of the foot bed, which is then adhered to the outsole unit. Voids forming channels in the top side of the outsole unit allow the passage of the strap below a user's foot. The continuous strap comprises the entirety, or part, of the total sandal strapping system when combined with fixed portions of strapping. This construction can be used to construct flat, low, medium or high heel sandals. Further, this construction method allows for single point adjustability at the buckle.
