APL Women's Streamline Shoes APL Supports Breast Cancer Awareness Month with the Limited Edition Streamline in Fusion Pink / White / BCA. APL is always pushing the limits of what's possible in performance. 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. The Limited Edition Streamline in Fusion Pink/White/BCA running shoe features special detailing including a tonal fusion pink upper along with a bleached pink ribbon logo on the heel- all in support of Breast Cancer Awareness Month. 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. The midsole sits atop a lightweight, two-piece rubber outsole that provides excellent traction along your journey.
