The new Vibram® Arctic Grip outsole technology is designed to withstand the most extreme winter conditions, providing traction and stability when things get icy. Arctic Grip is Vibram's most advanced cold-weather gripping system for slippery, wet, and freezing conditions. A thermochromatic lug turns from white to blue at 32° Fahrenheit as a sign for icy temperatures. Exclusive to Wolverine Worldwide through Fall 2017, it will be featured in Merrell's ICE+ Series.
A good example for the transferal of technology from the automotive to the outdoor segment.
