La Sportiva Women's Stream GTX Walking boots (37, grey) - The lightweight Women's Stream GTX walking boots from La Sportiva are made of a light mesh with stabilising Nano Cell 2.0 technology. The Gore-Tex membrane underneath is both breathable and 100% waterproof, so regardless of whether you're trudging through puddles, snow or wet grass, the Stream GTX will keep your feet dry. Thanks to the Gore-Tex Surround technology, both heat and moisture can escape through aeration channels within the footbed and midsole. That way, the interior of the shoe will stay fresh and comfortable. As for the sole, La Sportiva opted for a Vibram XS Trek outsole, cushiony EVA and an Ortholite footbed, which provide both excellent traction and cushioning.
