Yes. The impact goes into that big cushiony foam, bro.
You are mistaking pressure with force. This is the same reason that football concussions increase with better padded helmets. People think they can hit each other harder because the force isn't felt but it is still there.
Ummm no...the person giving lessons in physics should open a textbook to elastic collisions. You also don't understand pressure or force.
The big difference in cushioned vs uncushioned shoes is how the shoes mold to your feet and that it lengthens the duration of your footstrike
To oppose gravity the same amount of force must be applied whether you are standing on a metal plate or a piece of foam so force is equal. Pressure = Force/Area, If you are stationary and the contact area between both surfaces is the same area then pressure is equal regardless of how soft it is. Now your foot isn't flat so your a softer shoe will mold to the bottom of your bony foot increasing the contact area and therein reducing the force per unit area or pressure (see what I did there...its called physics)
Things get a bit different when they are colliding i.e. jump off a box or take a step while running. The time is takes to slow down your mass and counteract gravity is lengthened as the material gets softer. Average impact force and peak impact force are 100% affected by how plastic(soft) and object involved in a collision is.
TL;dr This person does not know physics...
