Systems and methods for securing a removable heel that is otherwise removably attached to a heel receiver of a shoe. The heel receiver has a fixed hook portion and a movable hook portion including a body received by an internal cavity of the heel receiver and disposed opposite the fixed hook portion. The movable hook portion is configured to move between a retracted position and an extended position, where the removable heel is secured to the shoe when the movable hook portion is in the extended position. Securing the heel includes inserting a locking pin into the internal cavity to prevent movement of the hook portion from the extended position to the retracted position.

There is an article of footwear that may have an interchangeable, height adjustable heel. The article of footwear has a recess in the heel portion. The height adjustable heel engages and is secured to the article of footwear by way of the cylindrical recess. The interior surface of this recess is preferably threaded, although it may have some other property that also enables securement of the height adjustable heel. The height adjustable heel has a connecting section and a base section. The connecting section engages the cylindrical recess. The base section can be of varying sizes allowing the article of footwear to take on a number of appearances and be worn in a variety of settings.

A footwear article includes a hinged portion in a heel region that may be biased in various positions to increase or decrease a size of a foot-insertion opening. The hinged portion may be arranged in a first position, in which the hinged portion is more upright and is in position to cup a wearer's heel or Achilles region when the footwear article is worn. In addition, the hinged portion may be hingedly rotated downward or rearwardly (e.g., away from the foot-insertion opening) to a second position, which may increase a size of the foot-insertion opening and/or may change an angle along which a foot can pass through the foot-insertion opening when the footwear article is being donned or doffed. One or more elastic members may be attached to the hinged portion and to some other portion of the footwear article to bias the hinged portion.

The present application discloses a retractable high heel for a shoe comprising a shoe base, a heel and a locking mechanism. The shoe base is coupled to a bottom surface of the shoe. The heel comprises a protrusion. The locking mechanism comprises a guide and a rotating shaft. The protrusion is slidably coupled to the guide. The rotating shaft is coupled to the guide. The protrusion is coupled at one end of the guide when the retractable high heel is at an extended state, wherein the protrusion is coupled at another end of the guide when the retractable high heel is at a retracted state. The shoe with the retractable high heel is also disclosed.

A heel structure with an adjustable height includes a support rod, adjustment rod, and retractable element. The support rod is penetrated by a through hole. Tracks and engaging grooves are disposed on the wall of the through hole. The engaging grooves are in communication with the tracks and run horizontally. The adjustment rod penetrates the through hole and undergoes displacement. Resilient engaging bumps are disposed above the adjustment rod and thus resiliently pressed within the tracks. The tracks abut against the engaging bumps such that the engaging bumps retract. The retractable element is rotated such that circular pipes of different diameters decreasing downward and stepwise are fitted together so as to be folded and unfolded. A hollow-core mounting region is defined centrally at the circular pipes. A fitting hole is disposed at the lowest circular pipe and fixedly disposed on an outer wall of the bottom of the adjustment rod.
