The North Face Nuptse Mule in black delivers lightweight warmth and everyday versatility with heritage Nuptse DNA. Built with a 100% recycled PET ripstop upper, these slip-ons are insulated with 550-fill goose down—responsibly sourced or recycled—for reliable comfort in cold conditions. A foldable heel design lets you wear them traditionally or slide them on as mules for quick transitions. Webbing pull loops at the heel and instep make them easy to get on and off, while the durable rubber outsole—made with up to 20% recycled rubber—provides protection and traction indoors and out.
