Abstract: An adjustable modular shoe system includes interchangeable structural sole portions and an expandable expanding portion for enabling incremental resizing across both width and length vectors. Rigid sole portions in an array of sizes feature attachment points for securing locking mechanisms that couple to opposing plates arrayed along the bottom of an inherently stretchable expanding portion. Selectively positioning customized locking mechanisms having adjustable fixtures influences expansion forces applied to the coupled upper plates. This allows actively and continuously modulating expanding portion fit even after securing a given sole size. Different locking mechanism number, location, and bridging configurations transmit vectors parsed across zones needing more growth allowance compared to areas better retaining proportional shape. Incrementally tuning shoe sizing avoids one-size-fits-all industry increments dictated independent of anatomy.
