Trail Z3 Design Notes
DROP: We built a 5mm drop into the Trail Z3 to reduce the chance of a negative heel angle during impact.
MIDSOLE DESIGN: Rocker and full-contact outsole smooth the transition and enhance stability. According to our recent paper on arch compression, forces on the arch are greatest during the push-off phase of your stride (not the impact phase). Many shoe designs carve out the arch area, which can collapse and exaggerate pronation. The Trail Z3 keeps the outsole area under the arch filled in to provide support during push-off, precisely when you need it most.
