APL Athletic Propulsion Labs designed these 'Streamline' sneakers as a lightweight and performance-driven running shoe. Made from black 'Aero Lux' ripstop for breathability, they're trimmed with tonal rubber and set on chunky 'Future Foam' soles that promote forward motion and energy return. They have newly-developed 'Soufflé' sockliners for additional comfort and integrated laces for a secure and customizable fit.
