The APL Streamline sneaker is built for pure performance. A newly-developed midsole offers superior comfort, cushioning, and speed with each stride. Horizontal channels carved into the midsole surface help smooth airflow. Lightweight woven textile combines with thin layers of support to improve airflow around the foot. Strategic reinforcement zones offer support with desired ventilation. An integrated lacing structure allows for customized fit. A microfiber collar and 3D molded heel provide friction reduction and incredible comfort.
