The Women's Nike Vomero Premium 'Oreo' puts two Air Zoom units inside ZoomX foam, and both sit visible through the side of the midsole. That's more cushioning than most running shoes bother with, and the stack under the foot makes the case before you get to anything else. Speckled flecks scatter across the midsole and climb onto the upper, thinning as they go. It's built for distance and wears fine without any.
