- UGG. 1115834 STT. EMMETT DUCK BOOT. STOUT. 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 -25.6 degrees 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.
