From the Lotta From Stockholm website: Lotta From Stockholm Swedish clogs are crafted with love and care in Sweden using vegetable tanned full grain Italian leather for the uppers and seasoned Swedish Alder from sustainable FSC managed forests for the base. A 5cm (2 inch) heel and 2cm (0.75 inch) platform provides enough height to allow the properly shaped footbed to be formed which includes both a pronounced arch support and a big toe indent for easier walking.
