A few millimeters at the heel

Small heel geometry is a Magnitude input. The bidirectional chain rewrites moments and the cup’s contact. Not formal medical advice.

No drop: heel nearer the ground plane. Cup contact sits in a different qualitative direction. Same person, different geometric boundary. Ground arrow is GRF (walking peak 1.0–1.5 BW). Do not mix GRF with joint-reaction force. Labeled schematic, not measured anatomy. Not formal medical advice.
