The UGG Women’s Classic Ultra Mini is the boot everyone’s been trying to get their hands on. It takes UGG’s most iconic silhouette and cuts it down to an ankle-height shaft, so you get all the signature sheepskin coziness with a sleeker look that’s easier to slip on and off. Genuine sheepskin keeps your feet naturally warm without overheating, while a cushioned wool-blend insole and flexible, ultra-lightweight sole make it comfortable enough to wear all day.
