The UGG Neumel boots for men are crafted with premium dark brown suede, known as chestnut. The suede is soft to the touch and adds a luxurious feel to the boots. Like many UGG boots, they feature a sheepskin lining on the inside. This lining provides unparalleled warmth and exceptional comfort for your feet, while keeping them cozy in cold temperatures. They have a pull tab at the back, adjustable laces, and stitching details for a high-quality finish. The combination of the cushioned sole and sheepskin lining creates an incredibly comfortable wearing experience throughout the day..UGGs feel snug at first, but the lining expands with wear. We recommend your usual size.
