The Red Wing Shoes Ice Cutter is without a doubt the ultimate winter boot. Back in the days the Ice Cutter was used by people fishing in the Mississippi River. These men would cut holes in the ice during the rough Mid-West winters so they could still be fishing in the frozen water. The Red Wing Ice Cutter comes with a Vibram out-sole that provides grip on any piece of cold and slippery winter ground. On top of that the Ice Cutter has a 100% woolen lining that will make sure your toes stay on there, although minus 30 degrees Celsius would normally make sure you would not feel your feet at all.
