APL is always pushing the limits of what’s possible in performance and our newest introduction the Streamline is our purest, 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, we created a completely new midsole and outsole made from our newest compound; APL FutureFoam.
