The shoes for Sheik are actually boots with a lycra material (bathing suit type material) stretch over them of course sew in the proper pattern and glued into position.
As far as dirtying it up naturally over the course of cons and such it has gotten some wear and discoloration. Just this past week I added a new grass stain to the right leg. >.> which the photographer promptly tried to remove with a tide-to-go pen until I objected. XD
I also found three more holes that need patching...such is the nature of stretchy material when it is pulled. I do have more newer photos in my DA gallery if anyone wants to view more.
