Eagerly conforming to every terrain contour underfoot, the La Sportiva Helios 2. 0 Women's Trail Running Shoe offers highly flexible traction within a minimalist, trail savvy design. The key to its all terrain prowess lies within its VA wave sole, which aggressively grips variable trail surfaces without slowing you down with excess bulk. FriXion AT rubber ensures sticky grip on rock outcroppings, gravel lined paths, and chunky, off camber trails alike. HyDrain mesh and wicking AirMesh along the upper maximize breathability, keeping your feet blissfully cool during stifling summer runs, also dispersing water when you encounter shallow stream crossings on the trail. The Fast Lacing System enables a near perfect fit, all without fumbling with pesky laces or having to re tighten throughout your run. Because you'll be running across formidable terrain, La Sportiva equipped the Helios 2. 0 with their MorphoDynamic midsole, which strikes a nice balance between responsive cushioning and smooth impact absorption.
