Our footplant and stride is unique to each of us. The real Damar Hamlin's right foot is everted, meaning it points out. He has a long, lean, lanky build, with long legs, and he walks (even as positioned in a still photo) as a lanky person would. The "recovered" Damar, even in this still, does not seem to have the same build, his legs are shorter, and his right foot points straight ahead -- it may even be a tad inverted, as suggested by his stride.
