Sheepskin boots are footwear made from the soft, warm hide of sheep. They are often lined with wool, providing insulation and comfort, making them popular for cold weather. The natural properties of sheepskin help regulate temperature, keeping feet warm in winter and cool in summer. These boots are commonly associated with brands like UGG, which popularized the style in the early 2000s. Sheepskin boots are typically designed for casual wear and can be found in various styles and colors. They are valued for their durability and comfort, making them a favorite choice for many people.
