APL STREAMLINE Review! $300 Running Sneaker w/ FutureFoam 。APL is always pushing the limits of what’s possible in performance & the newest introduction the Streamline is our purest, most purpose built running shoe to date. The APL FutureFoam™ running midsole compound was developed to provide exceptional compression, rebound & energy return. 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. The upper of the APL Streamline continues the lightweight story using our newest upper innovation, APL AeroLux™; a combination of materials all working together to provide ultimate performance and comfort. APL AeroLux™ combines a lightweight woven textile that is breathable & strong with thin layers of support & vector flow lines to improve airflow around the foot & reduce drag. The Streamline upper features strategic areas of reinforcement to give you the support that you need with the ventilation you desire. The integrated lacing structure allows you to customize your fit to keep your shoes as tight or as loose as you’d like. The Streamline features a Microfiber collar & tongue trim along with a 3D molded, padded heel to reduce friction and make all the inner touch points incredibly comfortable.
