There's a couple of really good tutorials on making the hooves from boots. I'm planning on using parts of both tutorials, plus adding additional support for her feet, but yes, the plan is for her heel to no be touching the ground. If I had $300+ to drop on them, there's a seller that does custom shoes that have hooves & they look incredible.
