The body of these clogs is made out of light yet strong poplar wood. Unlike most clogs, the leather uppers are not machine-tacked on to the wood, but are nailed on by hand. Uppers and lining are both low chromium barrel tanned. Both leather and wood come from Italy and the clogs have been hand-made in Hungary. The outside sole is of long-life rubber. The sticker on the heel serves to conceal a characteristic tiny hole in the wood caused by the manufacturing process.

Founded in 1885 by the shoemaker Heinrich Adolf Berkemann in Hamburg and now based in Thuringia, Berkemann has developed shoes that are more than sturdy, suitable wooden shoes. The Berkemann shoes feature the patented "5-phase footbed": It is shaped to support the natural walking motion and actually trains the foot and leg muscles.
