APL is always pushing the limits of what’s possible in performance and the newest introduction the Streamline is the most purpose built running shoe to date. A streamline, by definition, is a design that presents very little resistance to a flow of air, increasing speed and ease of movement. To achieve the superior comfort, cushioning and speed that the APL Streamline delivers, a completely new midsole and outsole was created from a new compound; APL FutureFoam.
