The Saucony Wmns Liberty ISO won the Runner's World 'Best Debut' sneaker in 2018. Capturing the reason for its success, the women's running shoe is equipped with a stretchy, engineered mesh upper for a dynamic, flexible fit. Bridging the gap between the upper and responsive EVERUN midsole, an EVERUN topsole adds extra cushion below. A medial TPU guide adds just a touch of structure to promote maximum mileage while zigzag lugs below grip the surface.
