System and method for assessing wear on the tread of a shoe for limiting slip and fall risk

A system for monitoring a tread of a shoe to mitigate slip and fall risk, comprising:

• a frame member;
• a waveguide coupled to the frame member, wherein the waveguide and the frame member are structured to support the shoe when an outer sole of shoe is in contact with a surface of the waveguide;
• a light source structured to provide light within an edge of the waveguide such that the light will be internally reflected within the waveguide;
• an imaging device structured and configured to generate an image of the outer sole of the shoe when the outer sole of shoe is in contact with the surface of the waveguide and the light is being provided within the waveguide;
• and
• a controller structured and configured to:
• (i) receive image data based on the image of the outer sole of the shoe;
• (ii) determine from the image data a largest worn region size for the shoe;
• and (iii) determine a slip risk for the shoe based on the largest worn region size.
