The women’s Ultraboost X Running Shoes were created to help you take the lead. Adidas designed these shoes with their foot-hugging motion capture technology. They feature lightweight uppers that deliver performance while comfortably contouring around your foot. Dual-density 3D heel counters were designed for a woman's heel, increasing stability while allowing for optimal achilles movement. Energy-returning Boost cushioning amplifies every foot touchdown. Super-grippy outsoles, built with a combination of energized Stretchweb and high-traction Continental rubbers, grab both wet or dry pavement.
