Illustrative profiles, not photographs: drawn from published stack heights and photo estimates of the unloaded shoes on a common length (300 mm), heels aligned, toe to the left; dots mark where each toe rocker starts; the dotted vertical line is under the heel bone (12 % of length), so a heel curve reaching past it is a bevel in front of the heel bone. Dotted lines use typical values where a shoe has no measurement. Exact values are in the table below.
