No More Shoe-Related Back Pain: New St. Petersburg Tech Rewrites Fitting Rules

Engineers from the Saint Petersburg State University of Aerospace Instrumentation (SUAI) have developed a neural network designed to automate the selection of footwear based on individual anatomical parameters. The digital service analyzes a photograph of a user's foot to generate a list of shoe models that match their specific physical characteristics, aiming to reduce errors in choosing athletic and everyday shoes. The tool targets common fitting difficulties caused by flat feet, hyperpronation, or unusual foot width. According to the developers, wearing improperly fitted footwear can lead to chronic fatigue as well as pain in the joints and back. Technical Process and Data Scope To use the algorithm, a user uploads a photo of their foot taken against a light background and provides their gender and personal preferences. The system evaluates three primary metrics: the arch of the foot, the type of pronation, and the width.
