Engineered to meet the needs of a woman, the Merrell Women's Siren Edge 3 Hiking Shoes are a hiking companion that's good to have in gravel and on rainy days. The outsole provides extreme traction for sure footing, even after splashing through puddles or a stream. A contoured insole delivers light support for the arches and is removable if needed. Additional stability comes from an arch shank made of molded nylon. The uppers are made of mesh and synthetic material for a lightweight shoe that won't drag you down.
