About OpenSize

About OpenSize OpenSize is a global digital comfort validation system for footwear and apparel. We build the infrastructure that transforms local biomechanical measurements into globally comparable, data-driven comfort validation. Comfort has long been tested in isolated laboratories, markets, and user groups. OpenSize connects these local measurements into a unified digital framework — enabling comfort to be measured, interpreted, and validated consistently across products, morphotypes, and regions. Our platform integrates: digital biomechanics and user anatomy, digital twins of product internal geometry, real-world usage signals, and AI-driven comfort analytics. This allows brands to move beyond subjective fitting and isolated testing — toward validated comfort regimes that can be compared, scaled, and optimized globally. OpenSize does not replace physical biomechanical laboratories. It extends their role, amplifying their data into a continuous, global validation layer. Our mission is to define how comfort is validated — and to establish digital comfort validation as a new industry standard.
