Although i do agree that any running dog is far better off with great feet, I can honestly say i've seen some crackers with bloody awful feet!
This is an old post and without reading all back, i can only hope the dog was took on, made fit and tried, just because feet look bloody awful don't mean they are bloody awful...
As Stabba and others have said, this cross can suffer from poor 'lookin' feet but until you've tried em you'll never know how they perform..!
