APL Athletic Propulsion Labs - Streamline Rubber-Trimmed 。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 and strong with thin layers of support and vector flow lines to improve airflow around the foot and 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 and tongue trim along with a 3D molded, padded heel to reduce friction and make all the inner touch points incredibly comfortable.
