When you're representing the United States on the Karaoke stage far from home, guard against unseemly slipping with the The North Face International Collection NSE Traction Mule Slippers. Not only do the Traction Mules come with a 40% recycled rubber sole for ultimate traction on beer soaked barroom floors, but they'll keep your feet toasty on the long trudge home with 500 fill power down insulation. Talk about melding function with style; even the POTUS would tweet hugely positive things about these babies.
