How it compares

  • On Cloudboom Strike 2's heel-to-toe drop is 5 mm, lower than the catalogue median of 6 mm (14% of the 179 other current shoes are lower).
  • On Cloudboom Strike 2's heel stack is 40 mm, thicker than the catalogue median of 38 mm (62% of the 176 other current shoes are thinner).
  • On Cloudboom Strike 2's forefoot stack is 35 mm, thicker than the catalogue median of 31.5 mm (76% of the 171 other current shoes are thinner).
  • On Cloudboom Strike 2's weight is 198 g, lighter than the catalogue median of 269 g (8% of the 167 other current shoes are lighter).
  • 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.

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. On Cloudboom Strike 2: heel 40 mm, forefoot 35 mm (drop 5 mm); toe rocker 33 % of length, radius 38 % of length; heel bevel 15 % of length, 27 mm high at the back, reaching in front of the heel bone (the sole still curves up under it: a heel rocker). 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.
