Danner's most popular work boot - now built in Portland, Ore. Danner has developed a new Vibram Quarry outsole and upgraded the midsole to a single, solid piece for increased longevity. Danner has also updated the collar liner to be instantly comfortable and re-engineered the placement of the triple-stitching to reduce wear and tear over time. Using their universal 610 last, the US-made Quarry has the same fit and feel as its predecessor.
