Inspired from Chippewa's great Logger heritage the lace-to-toe construction is a classic iconic style that comes with a removable kiltie. It provides greater stability around the foot, ankle and calf while traversing any terrain. Made with the Chip-A-Tex® breathable waterproof membrane, water is locked out of the boot by the membrane shield but air passes through from the foot for maximum comfort. Thinsulate™ Ultra is a lightweight, breathable, and moisture-resistant insulation. Thicker and loftier than regular Thinsulate™, Thinsulate™ Ultra provides greater warmth and comfort, yet it's still thin enough to allow complete freedom of movement.
