UGG men's slip-on sandals in black are made from brushed leather. They feature a UGGplush™ recycled wool and TENCEL™ Lyocell lining for a soft, warm feel. A sheepskin insole offers instant comfort, while a lightweight EVA or Treadlite by UGG™ sugarcane outsole provides plenty of cushioning and traction for urban wear. An embossed logo and recycled polyester trim highlight the precision craftsmanship.
