Why doesn't a/c blow more air directly on the floor and is there a fix

What is your question?

The bottom box or vent assembly has 3 outlets. 2 very small ones that barely trickle air to the floor and one much larger opening that blows air over the top of my feet. In the winter my feet are cold because the floor is cold without much warm air blowing down.

What makes this problem better or worse?
