Designed for shorter ground contact and more air time, this running shoe features data-driven construction engineered for the biomechanics of a woman’s foot. Perfect for: Female runners looking for gender-specific biomechanical support and propulsive strides in a shoe made with recycled materials to leave smaller footprints. Upper: One-piece engineered mesh molds around the foot for a breathable, secure fit. Lightweight materials in the heel foam, heel lining, tongue and inner reinforcement provide distraction- performance that won’t weigh you down. Sole: A fork-shaped nylon-blend Speedboard® with enhanced stiffness in the midfoot assists in forward propulsion. The full-foot CloudTec® sole molded from Helion™ superfoam puts softer, more stable landings under every stride.
