Established in 1923 in Jetzendorf, Germany, Lowa is the only outdoor boot manufacturer to have achieved ISO 9001 status for the highest quality construction and process standards. The longer-lasting boot manufacturing results from the PU (polyurethane) that makes the boots so favorable. It's the most durable material available for a sole.
For more comfort, Lowa uses a softer PU (polyurethane) in the soles which provides better shock absorption and optimal foot comfort.
