The Original Slipper Sock--over 40 years and still going strong. Astronauts have worn them on shuttle missions and aboard the International Space Station! How cool is that? Made of sustainable, natural all-weather fibers, they’re perfect for downtime on a frosty weekend, or just lounging around the pad all year long. The suede leather sole makes it ideal for treading on your hardwood floors or a quick trot to grab the mail. Comfort out of this world? You bet. Because down to earth guys like you deserve nothing less.
