About Martin Natur
In 2024, Iris Mesenbrink took over the “Martin Natur” brand for the adult shoe segment with “Pantolinos Manufaktur GmbH”, which has been producing baby shoes from the same natural leather in Germany for over 20 years.
The company headquarters has been moved to Germany, but the connection to the Spanish production plants remains. Our models continue to combine high-quality, vegetable-tanned cowhide from Germany with fair production in Spain.

How do I properly care for leather shoes so that they last longer?
