These shoes will work with Poser 11 or Daz Studio 4.10.
I made the Daz Studo version of these shoes with Daz Studio version 4.9. But, I call the items for version 4.10 formality. Because DAZ3D doesn’t recommend to use the old program. And, Pranx 2 is a figure tested with the version 4.10 (actually version 4.11 public beta).
The Poser version will work with the version 9 or 10. But, the old programs will warn “this is a new version’s item”.
