I dont see it as a problem. See hoe the front of her hooves match the angles of her pasterns? If you have too low of a heel, and too long of a toe, you would notice that the angles don't line up, which can cause stress to her tendons and also her toes. I think she looks just fine. You can always help her out with trimming, by taking little from the heel each time and snipping the toes, but to me she looks normal! :) I wouldn't let that deter you from purchasing her. She is a beautiful color. :)
In riding, a horse's energy is like a river- guided by the banks but not stopped by them.
