I am experiencing the same issue, however I do not believe that the boots are showing through. In fact it looks like some sort of "tribal" pattern if you will, that has been added to this skin (or was always there, just invisible). And the change in the color palette had made bad... worse.
Although I disagreed with calling them "TNG" pants, do to the fact that they are lacking "division colors" on the bottom yet the admiral's pants has it, the old style was a far sight better than these new ones.
And another one to report the same problem. I deleted the texture files in the installation to redownload the newest ones using force verify in the launcher options. Same threadbare looking trousers.
I did not purchase the TNG romulan outfits, this problem is not caused by that.
They've been broken since May. Doing a search, I've counted over a dozen threads with zero response to this question. I know you guys have bigger fish to fry, but a simple acknowledgement of, "We've added it to the whiteboard" would be nice.
Apologies if there is already a thread regarding this. I did look but was unable to find anything.
What has happened to the TNG Split pants at tailors. They are just oh so wrong now. the texture, the color (yes I know you can change color) but there is also some kind of pattern to them around the shin ankle area.
