NEW.The APL Techloom Zipline introduces new construction techniques to further improve performance. Featuring a seamless TechLoom construction the single layer upper provides lightweight breathability throughout, with engineered ribbing along the tongue and collar to provide stretch where it’s needed. The new APL TechLoom Ziplines completely surround the upper, providing both lateral and longitudinal support without compromising flexibility. The hollow cord APL TechLoom Ziplines keep the weight low and shoe balanced to help you perform your best. The sleek upper is fitted atop the maximum cushioning APL FutureFoam midsole, with internal Souffle sockliner for long-lasting and responsive cushioning. 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. The all-new proprietary APL Soufflé sockliner provides a final layer of long lasting, superior cushioning that makes this incredible performance runner have the step in comfort of a recovery shoe.
