One a few times but in great shape - see pictures for signs of wear. Gorgeous pink / purple / mauve color! 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. 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 edges. 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.
