Abstract
A footbed for a modular shoe system, a modular shoe system, and an interlocking fastener system for a footbed or for a modular shoe system, are provided. The interlocking fastener system includes a plurality of interlocking elements on a footbed configured to interlock with a plurality of complementary interlocking elements on a shoe base to releasably secure the footbed to the shoe base.

A footbed for a modular shoe system, the footbed comprising:
- a top surface;
- and
- a bottom surface;
- wherein the bottom surface comprises a plurality of integrally-formed first interlocking elements configured to releasably secure the footbed to a plurality of second interlocking elements of the modular shoe system;
- wherein the plurality of first interlocking elements comprise rows of concentric ovals interconnected into a first wave pattern;
- wherein the plurality of second interlocking elements comprise rows of concentric ovals interconnected into a second wave pattern that is complementary to the first wave pattern;
- and
- wherein the concentric ovals of the plurality of first interlocking elements meet at a tangent with the concentric ovals of the plurality of second interlocking elements when the plurality of first interlocking elements and the plurality of second interlocking elements are interlocked.
