Boulet do in fact make boots. But they do not offer any line of combat or tactical boots on their website. Even their cowboy boots don't seem available for direct purchase -- they direct you find yourself a local dealer in tack and western gear. So even if you wanted to, for some strange reason, purchase a version of the issue boots direct from the manufacturer, you can't.
There are any number of companies in Canada that will mail order you a decent pair of boots. I'm not in the advertising business, but PM me if you want specific links to companies I've dealt with in the past.
