So I've reported this using /bug but I also wanted to provide a screenshot example of this issue.
To be honest, this issue has been bothering me since the Crown Store started rolling out costumes, and it has prevented me from wanting to purchase a number of costumes that I otherwise quite liked on my character -- including the Hero costumes.
The core issue is that Orcish male characters with large feet (maximum sliders on Height and Foot Size, though experimentation has found the sliders have no actual impact on this issue) end up with teeny tiny boots comparative to other footwear, or even their bare feet. Usually this impacts width, but sometimes also length.
This affects Austere Warden (severely), Majestic "Dune Rider" Ensemble (slightly), and "Vested Interest" Banquet Garb (slightly) from current offerings. I also remember specifically not purchasing the Covenant Hero costume because of this issue, and I recall this also being a problem with some of the pirate-themed costumes that are no longer in the Crown Store (also costumes I considered purchasing, but declined because of this issue).
Since the Warden Costume was one of the incentives for the pre-order, I now feel as though the pre-order was devalued because I cannot enjoy this particular costume -- I'm particular when it comes to poor physical proportions.
I do realize this is a cosmetic issue, and is thus low-priority, but I'm hoping that it will be a fairly simple fix in terms of adjusting a few values on the way the mesh is applied to orcish males. You've given attention to other sizing issues in the past for clipping and such, so I'm hoping this might be put into the queue for a fix on your next pass of adjustments to the mesh sizes.
I currently do not know if other races, genders, or size sliders are impacted by this, or to what degree.
