How it compares

Merrell MTL SpeedArc Peak's heel-to-toe drop is 6 mm, about the catalogue median of 6 mm (25% of the 179 other current shoes are lower).
4 shoes with similar geometry from other lines.

Differences smaller than the precision of the sources (about 1 mm of stack, 8 g, or the spread between photos for photo estimates) are reported as about the same.

Geometry

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

Dashed: average of the catalogue

Stack not published: typical heel and forefoot 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. Merrell MTL SpeedArc Peak: stack not measured; toe rocker 34 % of length, radius 48 % of length; heel bevel 9 % of length, 17 mm high at the back, ending behind the heel bone (only the back edge is rounded). 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.
