Fine-tuning method for sole pressure balance inside the shoe when wearing arch appliance shoe set

A fine-tuning method for sole pressure balance inside the shoe when wearing an arch appliance shoe set, in which a sole unit of said arch appliance shoe set includes an arch appliance, and the fine-tuning method comprises the following steps: initially printing a foot chart: print an initial foot chart having a pair of footprints of user; preliminary analysis: based on an analysis model, initial information of footprints on the initial foot chart is analyzed, and based on this initial information to build an initial adjustment data for foot portions that need pressure adjustment; and initial adjustment configuration: based on the initial adjustment data to correspondingly install a pad unit respectively on sole unit of a pair of arch appliance shoe set. The present invention, based on the user's footprint conditions, correspondingly installs a pad unit on the sole unit so that when stepped, the sole pressure will reach balance from imbalance according to ergonomics and engineering.
