I originally bought this boot for dirty work and mild hiking up the mountain. I have never owned a Timberland boot before, only Coleman and a few cheap off brands I never heard of, so naturally I was much more excited to put this boot to work. The exterior of this boot is made with 100% leather, a tough under fabric, a tough black accented rubber composite on the toe and heel making this boot sturdy in the front and back. The sole is a slip and oil resistant hard rubber with enough gripping points for all types of surfaces.
