Geometry

Front: toe rocker shorter longerRear: heel stack lower higher not measured

Dashed: average of the catalogue

Toe rocker not measured: typical curve drawn

Illustrative profile, not a photograph or scan: drawn to scale for a 300 mm shoe from published stack heights and photo estimates of the unloaded shoe (under body weight the foam compresses and the curves flatten). The grey upper is a generic outline, not this shoe’s. Saucony Endorphin Trainer: heel 41 mm, forefoot 33 mm (drop 8 mm); toe rocker not measured, typical shape drawn; heel bevel 11 % of length, 21 mm high at the back, ending about under the heel bone. Dashed midsole: typical values stand in for what this shoe has no measurement of. Heel bone: 12 % of length from the heel, where heel stack is measured. Heel bevel and toe rocker are marked where each curve meets the ground; for the heel that is where the sole comes within 4.5 mm of the ground, which foam compression closes under body weight.

Percent values are relative to shoe length so they compare across images and sizes; widths in millimetres are lab measurements from the cited source, while toe tip and heel heights in millimetres are photo estimates converted for a men’s US 9 (assumed 300 mm long), so approximate. See how rocker geometry is defined.
