APL BLACK ATHLETIC PROPULSION LABS RUNNING SHOES TECHLOOM ZIPLINE SIZE: 9 WOMENS

APL TechLoom Ziplines fully encircle the upper, providing lateral and longitudinal support without compromising flexibility. Hollow APL TechLoom Ziplines keep weight low and the shoe balanced to help you perform at your best. The sleek upper fits over the maximum-cushion APL FutureFoam midsole, with an internal Souffle sockliner for long-lasting, responsive cushioning. APL's FutureFoam running midsole compound was developed to provide exceptional compression, rebound, and energy return through grueling testing over the past 24 months. The midsole surface features wind-carved horizontal channels to make each stride flow smoothly through the air. Additionally, a forward-leaning angled shank plate is sandwiched between the two-piece midsole to help promote forward motion at foot strike and accelerate the gait cycle.
