Houston, we’ve got a winner. Acorn’s famous Slipper Socks ($47) have been donning the feet of NASA astronauts since 1982, logging more than 500 million miles along the way. In fact, the Smithsonian Institution’s National Air and Space Museum has a pair on permanent exhibit.


We chalk up the Slipper Socks’ success among the stars to their humble, worldy focus on superior quality: a memory-foam midsole, featherlight EVA cushion layer, leather sidewall, and suede leather outsoles, which combine to offer stellar comfort and durability.
