For a general riding horse, she should be ok, but proceed with caution if you decide to do high-strain events with her. Just make sure you pay extra special attention to those front pasterns - they are prone to injury being angled that way. Just get her checked out by a vet and ask him or her what you can do to help prevent injury. :]
Again, like Barrelracer said, she may never be lame. It's just something that the conformational flaw lends itself to often. So just take extra caution and pay special attention.
Good luck with her, she is a gorgeous color!
