shaft height

How far a boot's shaft rises up the leg (ankle, mid-calf, knee-high, over-the-knee) — the boot-specific slot that a low shoe (a sneaker, a loafer, a sandal) has no analogue for, since it has no shaft. A kind-specific categorical setting on the spec sheet, eligible to vary like any facet; any realised split is a downstream Seedbed decision, not a Pool fact.

Shaft height is answered with one word chosen from the shaft heights list — the same word shared across every product that uses it.

It belongs to measurement — its measurable, physical facts.
