Merrell Oslo Waterproof - A smooth winter operator. Totally waterproof full grain leather, thick synthetic fur lining and Polartec® insulation gang up on cold and snow. A protective rubber rand brushes off impacts and abrasion, and dual density footbeds with integrated EVA wedge and Air Cushion midsole support and suspend active winter feet. Whatever the conditions, the Artrek lug sole will grip, not slip.
