The new La Sportiva Women's Crossover 2. 0 GTX Trail Running Shoe lets you transition from trail-running to snowshoeing and back again with ease. An airmesh and microfiber upper helps to maintain breathability, while still retaining the durability you need from a trail runner. A Gore-Tex Extended Comfort lining ensures that your feet stay dry and comfortable all day. The Frixion AT rubber sole gives excellent traction in anything from snow, to mud, and everything in between. As if all this wasn't enough, La Sportiva attached a water-repellent gaiter to really keep mud and snow from getting where it doesn't belong.
