Articles of footwear 1, and methods of manufacturing articles of footwear are disclosed. The footwear 1 comprises a heel portion 4 for supporting a heel of a foot 10 of a wearer. The heel portion 4 defines a channel 20 extending from a first opening 21 to a second opening 22. The openings 21, 22 are situated at laterally-facing surfaces 41, 42 of the heel portion 4. The footwear 1 may also comprises a fastening means 5 for fastening the article of footwear 1 to the foot 10 of the wearer. The fastening means 5 is arranged to extend through said channel 20 and, in use of the footwear 1, is fastenable around the dorsal region of the foot 10 of the wearer.

A retractable high heel shoe. The retractable high heel shoe includes a shoe having an upper portion extending perpendicularly upwards from a sole defining an interior volume that can receive a foot therein. A heel having a lower side is affixed to the sole at a rear side of the shoe. The heel includes a plurality of sections that can telescopically move between an extended position and a retracted position.

A method of forming a plate for an article of footwear is disclosed. The method includes applying a first strand portion to a base layer including positioning adjacent segments of the first strand portion to form a first layer on the base layer. The adjacent segments of the first strand portion having a greater density across a width of the plate between a medial side and a lateral side at a forefoot region of the plate than at a midfoot region of the plate and at a heel region of the plate. The method also includes applying at least one of heat and pressure to the first strand portion and to the base layer to conform the first strand portion and the base layer to a predetermined shape.

A method of forming a dual cure three-dimensional object by additive manufacturing may be carried out by mixing a first precursor liquid and a second precursor liquid to produce a polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g., a second reactive component) that is different from the first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction). In the foregoing: (i) at least one reactant of the second solidifiable component is contained in the first precursor liquid, and (ii) at least one reactant or catalyst of the second solidifiable component is contained in the second precursor liquid. Once mixed, the three-dimensional object may be formed from the resin by a dual cure additive manufacturing process.
