How it works

Method and source scope

Compare numeric labels against an inclusive range only when the row matches the documented group. Other groups and missing labels remain visible without a stiffness ranking.

Interpretation limits

Labels are not standardized stiffness units. No personal ability, weight or gender formula selects a boot. Confirm fit, group comparability and compatibility with a qualified fitter.
