The adidas Women's adizero Evo SL featured an engineered mesh upper with a speed aesthetic designed to get you ready for a fast session straight away. By reducing the stiffening element from carbon rods to a small midfoot nylon “dog bone” adidas have given the Evo SL a completely different feel from other LIGHTSTRIKE PRO shoes in the range. The outsole combines brand new and lighter clear rubber through the outsole, with proven Continental rubber through the forefoot giving the perfect blend of traction, durability and weight loss.
