You should give links to the boots and jeans you are using, so we can reproduce your problem.
Seeing this, I would say it is a problem with the costume mods that you are using rather than with the program.
If you use Vanilla shoes mods, they may use the same layers as the trousers. This can happen with my
Philia Boots for example, that will appear under trousers, because they both use the same costume layers.
If you use Loader specific mods, you shouldn't have this problem, because they can use more different layers than Vanilla and do not collide with other mods.
Unfortunately, I cannot help you with the Loader because I never used it!
Anyway, keep in mind that if the boots can appear over the trousers, they will still collide with it, and the trousers will appear under the boots, making something like this:

Dante's boots download page.
What you need in the first place is boots that will hide the trousers under them if you want to see the boots above the trousers, or boots that will be hidden totally by the trousers if you want to see the boots under the trousers.
Another important point is to find a mod that will just be put above the other mods and not replace them. It is an option that can be choosen by the modder and usually, it is not possible to know this before trying the mod.
In fact, SDT do not know what are boots or trousers, and cannot fold the trousers inside the boots!
