Foot Study New Build by ~TheCostumeArchive on deviantART
Digileg. A pair of these are just what you need for that Minotaur, Satyr, Werecat or other animal-like costume.
Digitigrade Stilts. Might be useful for a satyr costume at some point.
I have made a pair of these, and they are totally comfortable. I did make a few alterations to this artist's design, but she provides her twelve-page book as a free PDF download. Want awesome digitigrade stilts? Go here!
