A couple Dawnguard graphical glitches

[MidbossVyers]

I'm playing through Dawnguard, and I noticed 2 graphical bugs.  First of all, the texture on Dexion's feet through his sandals is distorted.  Barefoot males have the correct texture, so the problem might lie in the sandals themselves.  Secondly, the walls around Valerica's garden don't seem to load.  When I approach them, they block me as they do, so they appear invisible.  I noticed a similar glitch in Oblivion where buildings take a while to load and appear invisible a few seconds after entering an area, but in this case, the walls are still invisible even after a while. I'm using http://www.nexusmods.com/skyrim/mods/1947/ for male characters, but it seems that any shoes that have open toes or barefoot, such as Falmer boots or Dexion's Moth Priest sandals causes texture glitches.  This is purely for male characters only.  I have tested with both flesh-and-blood males (Dexion) and mannequins (which are only male in vanilla).  Is this what is causing the foot texture glitch?  If so, what is a better male mod?
