Combine soft, uniquely-durable, and breathable boiled wool with the foot support necessary to keep you healthy, energized, and comfortable all day long. Giesswein's natural wool footwear is not only healthy and comfortable, it is also environmentally friendly. While other companies are seeking to jump on the "green" bandwagon, Giesswein has been committed to the environment since their first batch of boiled wool was created in Austria in 1954.
