Lacrosse Ice King was developed and worn by gamesmen and outdoor enthusiasts in the midwest. This boot has stood the test of time and the test of ice and snow for generations. Drawing on naturally insulating properties, this boot combines a felt midsole, felt insole and a poly foam liner with 400G Thinsulate™ Ultra Insulation for the ultimate in warmth. The 100% waterproof rubber bottom with the ground-gripping Trac-Lite outsole will keep your feet dry and secure on slushy terrain. And just in case you hit a warm spell and the weather warms up to a happy –40 degrees, you can always remove the poly-foam liner.
