V3 is better about it in the foot department than earlier versions yes, but both Judy and Jessie are much better for making a modern jazz dancer (or someone just running or climbing barefoot), because of the extra flex ability the front of the foot has. You can take one of the ballet BVH files off the net, get the gross corrections done, apply to Judy and Vickie both, and just by adjusting the bend and slope of the toes turn that into a credible non-ballet dance routine. But Judy allows you actually shape the foot, spreading and twisting the toes in reaction to the motion of the body enough that you can actually risk low angle shots. Vickie's just isn't flexible enough to do that safely. You may not think about it, but the eye and mind notice and catalog....and a little thing like that can blow the illusion. That's why you see so many animations where no one takes their shoes off, or wears sandals. Getting it right takes time, and budgets usually require glossing over other things to concentrate on the hands and face.
