The earliest shoe sandals made from sagebrush bark date back approximately to 7000 or 8000 BC. They were found in the Fort Rock Cave in the US state of Oregon. The world's oldest leather shoe, made from a single piece of cowhide laced with a leather cord along seams at the front and back, was found in the Areni-1 cave complex in Armenia and is believed to date to 3500 BC. Ötzi the Iceman's shoes, dating to 3300 BC, featured brown bearskin bases, deerskin side panels, and a bark-string net, which pulled tight around the foot.
