It's easy to question your own sanity when you're grinding up seemingly endless switchbacks, but the rolling singletrack through alpine meadows that waits above will quickly reaffirm your decision to trail run. The Salomon XA Pro 3D GTX Women's Trail Running Shoe carries your feet through the highs and lows of your runs with a tough chassis that will bulldoze through those steep switchbacks and a Gore-Tex insert to keep feet dry after stomping through shallow creek crossings.
