Abstract

A method for determining best fitting footwear includes acquiring a static 3D scan of a user's feet; generating a static 3D model of the user's feet; modifying the static 3D model to generate a dynamic 3D model that corresponds to changed shape of the user's feet when performing an athletic activity; identifying a footwear that best matches the dynamic model; and informing the user of the footwear that best matches the dynamic model. Optionally, the static 3D scan is retrieved from a database, or generated on the fly, or based on images from a mobile device. Optionally, the dynamic model takes into account a type of athletic activity, a weight distribution of the user, a load on the feet of the user, and a motion mechanism and strike type. Optionally, the dynamic model modifies a foot length, a foot width at ball, and a foot width at bottom.

Dependent claims

A method for determining best fitting footwear, the method comprising:

acquiring, from a scanner, a static 3D scan of a user's feet in a static standing posture;
generating a static 3D model of the user's feet based on the static 3D scan;
modifying the static 3D model to generate a dynamic 3D model that simulates a changed shape of the user's feet when performing an athletic activity, including a simulation of a flattening of the user's feet during exercise and a simulation of peak dimensions of the user's feet during the exercise by scaling a length of each foot according to

informing the user about which footwear has a shoe last that matches the identified shoe last,
wherein the static 3D model and the dynamic 3D model use a set of polygons to form a skin mesh of a surface being modeled.
