US Patent 11771176 Footwear with aligned tensile restraints

A shoe may include an upper and a sole structure. The upper may include a shell and first, second, third, and fourth sets of tensile restraints. Each of the sets may have one or more tensile restraints extending over and/or through a corresponding portion of the shell. The shell may be engaged with the sole structure and define an interior void configured to receive insertion of a user's foot. The first, second, third, and fourth sets of tensile restraints may be configured so that, upon securing of one or more structures to tighten the upper and connect the sets of tensile restraints, two linear axes of tension with anchors located in the forefoot and heel region extend diagonally across the article from one side to the other.
