Need help - bad feet with UNPB

[Something02]

Hi. I've been playing modded Skyrim for a while, but I'm new to fiddling with body types, skeletons and physics and this is my first attempt at such a thing. I've encountered some persist problems with terrible feet and though I don't usually ask for help in forums, I'm at my wit's end. I'm using the latest versions of UNP Blessed Body with XPSME skeleton and HDT physics, and I'm consistently getting horrible foot seams on my characters that I simply don't know how to fix. Hoping someone can give me a hand. Attached are pictures and load order.

 

I'm a complete newbie to this, so if the solution involves BodySlide in any manner, I'd appreciate some detailed instructions on how to use it, since I've never done it before. I run generate FNIS for users every time I fiddle with the modlist, with the skeleton arm fix patch. I've also already tried installing new feet meshes, namely Halo's High Poly models for UNP, to no avail. New textures (namely Real Girls Realistic Body Texture for UNP UNPB and SeveNBase) do nothing either.

 

Also, if it helps, these are the options I'm choosing in the installation of those mods. I realize I might have made mistakes here:

 

For UNPB: "T/BBP or Bouncing" > "NSFW or Nude" > "TBBP Body" > "I have my own skeleton!" > (Animations) "Not installed" (I'm planning to use different animation mods, though this problem has so far prevented me from expanding my list.) > No textures, no idle animation and no patch.

 

For XPSME: "Skeleton Rig Map (HDT)" > No plugins > No magic nipple options > No extra animations > All extended monster skeletons > No first person or mounted combat plugins

 

Some help would be greatly appreciated, thanks.
