For those needing a safety toe and who work in extreme cold or have long periods of inactivity, our Steel Toe Hoffman Felt Lined Calk is a good choice. Built with a removable 9 mm felt liner, this boot offers warmth in the coldest conditions. A polypropylene inner liner wicks moisture away from your feet to keep you dry. A rebuildable and improved industrial grade rubber bottom eliminates cracking and premature rebuilds. Replaceable calks and a triple stitched, 7 oz. leather upper make this boot a great value.
