Reebok no longer uses the original hexalite honeycomb pods that were softer plastic. I think they switched to a harder plastic because it is cheaper and easier to make. Plus, it holds up better when they insert them in the insoles for cushion. It was common to hear your Questions bottom heel make pop/squeak sounds once the honeycomb pockets break down.
The original design didn't need to have the white lines painted because the plastic pod construction naturally caused that contrast white line.
This new one looks to be a hollow airless grid that holds no air pressure. They just roll white paint over the top of surface to accentuate the hexalite pattern. Then they wrap it in plastic to make it look like it holds air.
One thing Reebok still does is paint the back of the hexalite bag. They did that to the originals as well. That midsole is all white, so, they add color to the back of those pods so the clear see through pods don't blend in.
