I'm working on my first suit and I've kind of hit a brick wall with boots, as well. It looks like Imperial Boots and Crowprops are the only two legit sources, but I could be wrong. I've seen mention of TKBoots, but it appears to be defunct. I'm leaning towards Crowprops because they actually tailor the shoes. I have wider feet so anything custom made is going to fit better than a standard shoe size.
