Brooks redesigned the Wmns Puregrit 4 as a universal trail running shoe for marathons and daily training. This women's rendition utilizes a breathable Air Mesh upper with hexagonal overlays for durability and a bright Nav Band for flexible support. Its BioMoGo DNA midsole is updated with a Tuned Density element for a custom ride that adapts to the runner's weight and gait. The blown rubber outsole is equipped with a 3D lug pattern for multi-surface traction.
