** odf**,

I'm not quite sure this could be called a rigging issue, but I'll mention it any way. In most figures the foot actor goes right up to the the toes. That is not the case in Antonia because of the Instep actor. It seems that when the Walk   Designer calculates a pose for the foot, it rotates the foot geometry down until the front of the foot is touching the floor. In most figures this is equivalent to touching the ball of the foot to the ground. In Antonia, because of the shorter foot, by the time the front of the foot is touching the ground, the ball of the "foot" (Instep) is below the ground and the bend angle of the foot is greater than would otherwise be the case.

There might not be any good fix for this, and I think we may just have to live with it, but I thought it worth mentioning so that you are aware of the issue.

The workaround I am using at the moment is to inject a different foot geometry, with one vertex pulled forwards to the toes. This kind of wrecks the foot geometry, but as it is the bottom of the foot, it does not really matter in a walk sequence where bottom of the foot is not usually visible.
