It is generally accepted that improper footwear design causes injuries and illnesses. Existing literature indicated that mostly static footwear fit has been studied to some extent, even though we are well aware that dynamic footwear fit is different. In addition to static fit, illnesses and injuries will occur due to dynamic pressure, friction, and foot movement beyond the normal range of motion. This study proposes a method for dynamic foot shape computation. The dynamic foot is generated by using multi-dimensional transformation of the 3D static foot based on the angular values of the foot movement. This provides a simple algorithm to deform the foot to create dynamic 3D foot shape. Result of this study is essential to build a model for dynamic fit computation.
