Etsy seller Oonacat makes custom fetish boots with hooves -- demon hooves, unicorn hooves -- that go for $900 a pair. Great for playing naughty podiatrist and agonized fetishist. There are also horns.

These are my newest creations, and I adore these little monsters. These Hooves are created with durability, quality, and artistic kickass beauty in their design. High attention to detail is what I love most about my Hooves, be it in the intensive process and creation, to the construction process, to the high quality of the materials I use, to the professional construction of the Hooves themselves, to the hoof tracks you will leave for those to follow... And follow they will...
