I'd suggest that you make only one toe group at the tip of the foot, just like Posette, and then manipulate the individual toes by way of morphs.  That way, when yo want to hide the toes for foot wear, all you have to do in uncheck the visability checkbox in the properties tab.  No need for special poses or anything.  Remeber KISS, there is virtue in simplicity.
