Here is the video from the Korkers web site about the new KGB boot.
The Aluma Trax sole is another new product from Korkers we are really excited about. A sole with maleable aluminum bars made to cut through slime. These soles grab rocky river bottoms extremely well. Wear and tear will only improve performance by increasing surface area. Inspired by Korkers aluminum bar overshoe cleats from years past, this outsole option provides sure footed traction in challenging terrain.
