In 1547 a member of the French court accompanied King James V on a tour of the Scottish kingdom. His published account of the trip mentions the "Wild Scots" (highlanders) wearing "boots made in an old-fashioned way, which come as high as their knees."

So apparently those high moccasins many wear at RenFairs arguably have some historic correctness, though who knows how the "old-fashioned" boots were constructed...!
