MODULAR INSERT SYSTEM FOR SHOE SOLES

摘要

A support customising system is described for a sole 1 of a shoe. The sole 1 comprises a relatively soft, resilient midsole 3 and an a harder outsole 4. Hard insert elements 5 are provided for inserting into vertical cavities 2 in the midsole 3. By varying the hardnesses of different inserts 5 in different vertical cavities, a precisely-tunable pronation control effect on the wearer's gait can be effected. First-order, second-order and third-order pronation control effects are described.
