The Fila R4 Womens Tennis Shoes are comfy and lightweight at the same time. Unlike the much heavier and more durable Fila R8 shoes, these R4s offer more mesh and cushioning. The midole uses SUPERACTION EVA for some nice cushioning . The outsole uses EverGrind, adding some resistance to hard courts. The bottom has a herringbone pattern.
