I've been getting complaints about these showing up on children and while nude. I've triple checked the Casp file and it's set accordingly, not to random and only YA/A. Is this issue my fault or theirs?

Dont think its your fault, there are some ugly files arround that can totally fuk up your game.
I had similar complaints with a female adult shower top replacement wich showed up on kids....
Since i only updated(and uploaded) the GEOM file it should be impossible that it would popup in a child section, but it did.....(because one smart ass enabled the nude female top for CAS and set it to all ages...)
You did include the meshes and the file is based on a male shoe so i wouldn't worry.

It's not your boots - there has been a set of those EA female boots floating around categorised for toddlers and naked since long before you uploaded these; they were one of the first recorded instances of the categorisation problem (e.g. here). People download them packaged with sims3pack sims without realising they're there - the actual problem file is the first on this list: http://crinrict.blogspot.com/2010/0...isiert-fur.html

Thanks, I didn't think so but I just had to ask to make sure.
