I just need some boots, and I had assumed that they where period correct. I have seen wood cuts of men in armour with kumund sticking out of the bottoms and had assumed that they where boots. Because I know from experience that you cannot where grieves on a hoarse with plain shoes.
Are you sure that the 'shoes' are not a part of the armor themselves? I believe there are extant versions of armor from the period where the pieces over the feet were styled to look like shoes (in fact, the entire set of armor was styled as a set of puff-and-slash clothing).
