Signature Crocs style gets a winterized update in the new Classic Lined Clog! Engineered for lasting comfort indoors and outdoors, the Classic Lined Clog features fully molded and easy to clean Croslite™ foam construction in the iconic clogs silhouette—now with a plush lining for added warmth. In 2021, Crocs became a 100% vegan brand, eliminating all animal derived materials from their products. Eliminating materials such as leather and wool reduces environmental impacts across areas such as emissions, waste, and water usage.
