Danners most popular work boot now built in Portland, Ore. We've developed a new Vibram Quarry outsole and upgraded the midsole to a single, solid piece for increased longevity. We've 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 our universal 610 last, the US-made Quarry has the same fit and feel as its predecessor.
