Does she toe in at all?
I've seen this before, on both front feet of one poor horse. He toed in very badly on both fronts and it appeared like someone had tried to fix that by trimming his hooves completely normally (or something, I'm no expert that's just what it looked like) and so his hooves looked straighter while his frogs still screamed "I toe in very very badly!".
I'm no pro though, I've just seem it before. That horse did go dead lame 3 weeks later but I don't think that had anything to do with his hooves being like that.
