in fact it is the hoof - for look like this. but the functionality is a platform without a heel, which shaped hoof. Therefore, I say that the issue moot
um. I think they're trying to say that the hoof it sorta like heels, only there's no actual 'heel' part of it, just the part that you put your toes on.
it looks like they're walking on their tiptoes? and the 'ankle' of the leg is actually their heel.
