Salomon XA Pro 3D Running Shoe Log your mileage faster with the Salomon XA Pro 3D Women's Trail Shoe. It's got a Contagrip® Outsole that delivers the traction you'd expect from a boot but instead the upper is a lightweight, breathable design more similar to a sneaker. So you get the support and protection of a 3D Advanced Chassis™ shielding you from trail hazards and supporting you in every step, and the mesh upper features Sensifit™ Technology designed to cradle your foot while keeping all the components of the shoe exactly where you need them for maximized performance.
