Our iconic heritage chukka gets a weatherized upgrade. A timeless boot made of rich, waterproof suede, it's lined in our UGGplush™ upcycled wool blend and finished with an outsole made from renewable, rainwater-nourished sugarcane for all-day cushioning and a signature Classic-like feel indoors or out. Spider Rubber™ outsole pods offer enhanced traction. Exceptional Traction Features an innovative outsole that provides outstanding grip. Weather Rated to -20ºC Cold-weather styles with this icon are rated for temperatures as low as -20°C (-4°F). Waterproof Features Designed to help protect against mild or moderate weather conditions, but not suitable for heavy precipitation. Features waterproof materials, and waterproof seam-sealed construction below the ankle. If present, zippers are treated with water-repellent coatings. Recycled Materials We repurpose once discarded fabrics and materials into new formats that would otherwise go to waste or be destroyed. UGGplush Lining Crafted from a proprietary blend of repurposed wool and produced fibers, such as Tencel or recycled polyester, UGGplush gives a sheepskin-like feel with reduced environmental impact. SugarSole™ The sugarcane in our SugarSole™ foam allows us to reduce dependency on fossil fuels by replacing petroleum-based ethylene, absorbing 1.6 pounds of CO2 for every pound of ethylene replaced.
