Don't let the weather hold you back from your normal runs and walks. We offer select models with a Gore-Tex® layer sewn in to help keep your feet protected on the run. Gore-Tex® is a waterproof, breathable fabric membrane that is able to repel liquid water while allowing water vapor to pass through, and is designed to be a lightweight, waterproof fabric. These shoes will have GTX in the name to identify they offer Gore-Tex waterproofing.
