NexGrip PathFinder 2.0
If you worry about slipping on ice, the NexGrip "Ice Pathfinder" is the answer to your prayers. A waterproof insulated winter boot, it has a patented retractable stainless steel cleat that you flip with your finger to bite into ice when needed and flip out of the way for more normal conditions. The forepart of the treaded sole is made of an anti-slip compound. The waterproof shell bottom has a leather-and-mesh side-zip shaft with membrane waterproofing and Thinsulate® insulation rated to -40 degrees.
