Authentic Heritage design meets weather-ready performance in the Emmett Duck Boot. Combining the flexibility and performance of a sports shoe with the stability, style, and functionality of a hiking boot, the Emmett is packed with high-tech features - from its seam-sealed waterproof leather upper to its cold-weather rating of -32°C (or -25.6°F). The dynamic support shank provides torsional stability over varied terrain, while the cushioned sole is equipped with specially-engineered tread to help prevent snow from getting caught underfoot. Additionally, the White Spider Rubber outsole features ice-gripping rubber lugs on the forefoot and heel, enhancing traction on wet and frozen surfaces.
