Geometry

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

Dashed: average of the catalogue

Heel bevel not measured: generic rounding 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. Salomon Aero Blaze 4: heel 36 mm, forefoot 28 mm (drop 8 mm); toe rocker 39 % of length, radius 59 % of length.

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.
