About Winter Shoes:
Winter shoes are designed to offer extra protection during cold and wet weather and extra grip and traction on wet or slippery surfaces. Winter shoes typically feature uppers made of waterproof or water resistant materials to keep feet dry and interiors lined with materials such as fleece or shearling to insulate the feet from the cold. Also, they may have high-tech synthetic fabrics for warmth and breathability.
