When winter digs in, the right liner makes all the difference. This 8 mm felt liner is built for your Greenbay 4 winter boots, keeping your feet toasty down to -40°C, whether you're shoveling snow or running to catch the bus.
Made from insulating felt, it traps heat while allowing your feet to breathe. And when it's time for a refresh, just replace the liner, not the boot. Comfort that lasts, season after season.
