I think I can see a difference in the back of his foot above the hairline, too. It is remarkable how much better his sole looks. Where is his left bar hiding?
Yea George! :) Is he landing heel first or toe first? I ask because he has those 'pointy' heel bulbs that lack from a springy fatty digital cushion...I know those too well ;) We are forever trying to build that up. I'm sure that will develop in no time. It's amazing how fast their feet can recover.
He is landing flat behind. He has awkward confirmation in his hind legs.
