When things get slippery, you need some extra traction to keep from landing on your behind. Kako introduced the Ice Trekkers Ultra, a line of personal traction devices base on the same techniques used for vehicle traction, which include studs, tire chains and cables. The Ice Trekkers are easy to use and excellent for gaining much needed traction for running, walking and hiking. Ice Trekkers Ultra are made from alloy steel beads with multiple cutting edges that provide a tenacious grip. For more information, contact: Kako International Inc. http://www.kakoicecleats.com
