A chassis for an article of footwear may include a base and a frame attached to a top side of the base. The frame may include a network of interconnected walls defining a plurality of cells, each of at least a portion of the cells having a bottom at least partially closed by an underlying portion of the base. A bottom of the base may be fixed with respect to a plantar section of an upper. A sock liner may be indexed to the chassis or to another footwear support structure. The sock liner may have downwardly-extending tabs configured to rest in cells of the chassis or in other cavities of a support structure.

Methods of forming an article of footwear using a multipart strobel structure and a resulting article of footwear comprising an upper with a transition strip are described. The transition strip that has an outer perimeter edge, an inner perimeter edge, and a width between the outer perimeter edge and the inner perimeter edge, with the inner perimeter edge defining an internal opening of the transition strip, and the inner strobel that has an outer perimeter edge. The inner strobel is positioned in an overlapping relationship with the transition strip and temporarily attached.

An article of footwear is configured to be worn so as to at least partially cover a wearer's foot. The footwear includes at least one optical fiber on an internal surface of the footwear. The at least one optical fiber is configured to project radiation having a therapeutic wavelength through the at least one optical fiber and toward at least one of the wearer's foot, ankle or leg when the footwear is being worn so as to at least partially cover the wearer's foot.

The present application discloses footwear comprising a body structure in which at least upper is made of one continuous folded composite material comprised of layered sheets of material.

The present Invention Comprises a Shoe, Boot, Sandal, type Footwear consisting of an

Actuated Heel Portion that may also contain a portion of Said Footwear's Sole structure. Heel Portion is affixed into place during use by way of: magnets, Velcro, hook and loop, Ball and socket or desired elements or mechanics so when manipulated in a downwardback-Motion against the Floor or Ground, will Unsecure Heel Portion to Remove Said Footwear. Electronics, Mechanics, Mechanical, Pneumatic, or Hydraulic Elements may also assist or Actuate Heel Portion to Open, Close or Intermediate Position upon Desire of Wearer.

Another way to achieve Same Benefit of Said Footwear is by way of Elements affixing on both Sides of Wearer's Ankle or the Area there of and extending under Heel Area and attached or Fashioned to or as part of Said Footwear in an Actuating Fashion allowing insertion and Securement upon desire.

Other ways of achieving same Said benefit of Actuated Heel Portion of Shoe, Sandal, or Footwear is by way of Spring Tensioning or assisting Hinge or Actuating point of Movement or about there of or by way of Assisting Said Actuating Point of Movement with Electrical, Electronic, Mechanical, Pneumatic, Hydraulic, Magnet, or desired Elements to Achieve desired results.
