So, I don't know if that is relative or absolute

If you have the option,  set the morphs to relative.  Rule of thumb in modeling,  relative for organic and absolute for inorganic.

Now,  relative and absolute are a side issue.  The main problem is Max's conversion to obj format.  Try importing your obj (the original boots) into uvmapper,  group it in uvmapper,  save out,  then import into Poser.
