Finished in black waxed calf leather (reversed waxed tanned). Extremely sturdy leather from Joseph Clayton & sons in Chesterfield, UK. Will not change much. You´d probably need an axe to scratch it. Hard to break in, hard to wear out. Triple layer leather sole. Pictured with a fully hobnailed leather sole, but that is way to extreme. We recommend a Dainite Logger rubber halfsole.
