Jumping to the late 80s for a minute here’s a 1988 vintage sneaker ad for the Turntec Road Warrior runners with Z0 2 technology.. Jerry Turner developed most of the classic Brooks brand running shoes.

"Stop taking abuse. ” Jerry Turner
Slam, bang, bang. It's positively abusive— the punishment your feet take when you run. So, when an advanced cushioning material comes along, you'd want it right against your foot where it will do the most good. That's why I've put my new ZO2 in the sock liner of my next generation running shoe, the Road Warrior.
Unlike gel or air, ZO2 is not buried in the midsole. In fact, it lines my famous Anatomical Cradle. It's my new ZO2 insert—right against your heel where it can absorb the most shock.
And then there's the Cradle itself. It's scooped out of the heel area of the midsole —so your foot rests in the midsole, not on it.
The results? More stability because the Cradle keeps your foot from moving inside the shoe. Better cushioning because it concentrates your heel's natural padding where it can work best.
I've even added my newly developed Poly-Lite midsole. The lightest polyurethane midsole material available to date! It is as light as E.V.A. but vastly superior in shock attenuation and durability. So check out my new Road Warrior where you buy athletic shoes. And forget about the abuse of running. In the Road Warrior, you won't have to take it anymore.
My Anatomical Cradle" is scooped out of the midsole so your foot rests in it, not on it, for more stability. And it improves cushioning by concentrating your heel's natural padding where it works best.
Z02 insert, effective cushioning where it does the most good: right against your heel.
