Ugg Classic Boot was originally designed on the California coast to keep surfers warm after an early morning ride on the waves. Since then, it has become a symbol of cool West Coast style. It's made from our famously soft lambskin that naturally wicks away moisture and regulates heat. You can wear it anywhere you want, both indoors and outdoors. This product was manufactured in a factory that supports women in our supply chain as part of HERproject. The initiative creates partnerships between brands like ours to empower women through training and empowerment in the workplace. The outsole of this product is either a Treadlite by UGG™ outsole or a SugarSole™ outsole. SugarSole™ is a sustainable foam made from sugar cane rather than petroleum-based ethylene to reduce our reliance on fossil fu.
