With ‘thermochromatic lugs’ that turn blue and a name like ‘Arctic Grip,’ it may be hard to view Vibram’s upcoming sole technology as anything more than marketing flair. But just wait until you try it on ice.Rubber and wet ice traditionally don’t mix. But at this year’s Outdoor Retailer Winter Market, Vibram installed a massive frozen block and encouraged people to hop on and test Arctic Grip. Almost immediately, an unrehearsed ‘WOW’ escaped the lips of the testers, as the magic rubber stuck on the slick ice with propensity rivaled by nothing short of metal spikes. It was so remarkable GearJunkie awarded it Best In Show.
