Cozy slippers by Acorn® have been worn by NASA astronauts in orbit and sherpas at Mount Everest base camp. Fortunately, Acorn is just as good at designing comfortable footwear for more down-to-earth itineraries. These shoes’ slip-on, metal-free design make them a perfect choice for smooth passage through airport security. The removable insole and EVA midsole offer lightweight performance and maximum cushioning so you can wear them all day. The moisture-wicking wool lining keeps feet comfortable, never too hot or too cold. Suede uppers are stain- and water-resistant, and the nonslip rubber outsole provides sure footing outdoors.
