Designed so you can go fast in the mountains, the Merrell Women's MTL Skyfire Trail Shoe is lightweight and has been created with a tear-resistant fabric and breathable mesh to ensure feet are quick, protected and cool. For a comfortable, supportive stride you can rely on an internal bootie and external rear sling that offers a locked-in secure fit for the whole foot, while an EVA foam midsole lends cushioning and stability as you take on even the most challenging of trails. Additionally, a Merrell mountain-grade Quantum grip™ rubber outsole provides an expert grip and traction on a variety of surfaces.
