This invention describes a lacing system for an object with two separate parts, each having eyelets. A main lace threads continuously through all eyelets, creating bridge sections, and a second lace then connects to these bridge sections. One end of the main lace is hidden inside a void within the object's body, accessible through an opening on its surface. The claims narrow the invention to a version where one of the laces is more stretchable than the other.
Why it matters: Since 2014, advancements in performance textiles and manufacturing techniques for integrating internal voids in flexible materials have made it easier to implement the specific stretch characteristics and hidden lace mechanism described. This could enable more durable or aesthetically refined versions.
