Don't be stopped by rugged trails and wet weather when you're wearing the La Sportiva Women's Stream GTX Boot. Featuring a Nano Cell 2. 0 upper--which uses breathable cells to offer high levels of ventilation--in conjunction with the waterproof, breathable Gore-Tex Surround membrane, your feet will be protected from outside water and exempt from overheating. Comfort is about more than staying dry, though, so La Sportiva added a TPU frame to wrap your foot in a supportive embrace, offering lightweight stability and responsiveness on rugged terrain. The EVA midsole makes each step feel soft and energetic, while the Vibram sole finishes the package with reliable traction, even on wet boulders and muddy trails.
