APL's newest introduction the Streamline is our purest, most purpose built running shoe to date in this exclusive colorway. 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. The APL FutureFoam running midsole compound was developed to provide exceptional compression, rebound and energy return through strenuous testing over the past 24 months. The midsole surface features horizontal channels carved by the wind to make each stride smoothly flow through the air. Additionally, a slanted, forward leaning shank plate is sandwiched between the two-piece midsole to help promote forward motion upon foot strike, and accelerate the gait cycle. DETAILS: - Maximum cushioning, two-piece APL FutureFoam midsole specifically tuned for running. - Slanted shank plate encourages foward motion upon foot strike. - Lightweight, solid rubber outsole designed for road and gym use. - APL AeroLux upper combines a lightweight woven textile that is breathable and strong with thin layers of support and vector flow lines. - 3D molded heel padding and microfiber collar edge. - All new proprietary 5mm APL Soufflé sockliner. - The 8mm drop from the heel to the forefoot places your foot in a natural position for efficient running.
