Knit upper
One piece of engineered knit, tighter at the heel and looser over the toes, where feet spread as they tire. A padded collar keeps the ankle still without pressing on it.
Six layers, glued and stitched into one shoe. Here is what each one does and why it is there.

Five thin straps a side run from the laces down into the sole. Pull the laces and the straps hold the midfoot, so the knit itself can stay soft.
A full-length carbon plate between the foam and your foot. It bends little at the forefoot and curves up under the toes, so push-off feels like a lever, not a squeeze.
Nitrogen-infused foam makes up most of the stack: 36 mm at the heel, 28 mm at the forefoot. Soft enough for kilometre thirty, quick enough to spring back.
A firmer layer of foam under the soft one. It stops the shoe rolling inward or outward when you land, especially late in a run.
Thin rubber with a shallow lug, thicker under the outer heel where most runners wear through first. Grip for wet roads, not for mud.
The sole curves up at the toe and a little at the heel. You land, the shoe tips forward on the curve, and the plate levers you off the toe.
