These ageless shoes were worn from the Stone Age until Classical Antiquity into the Early Middle Ages and possibly even later. A number of originals of this type have been excavated, among which an early medieval original from Ireland. These sandals are made of nibuk leather and have a rubber sole as an extra protection from slipping. The sandals are available in the sizes 36 up to 48.
