A high heel footwear including a heel tip assembly and a heel assembly. The heel tip assembly includes a top lift abutting against the heel, a rigid shaft member having a threaded portion, and a first wedge-lock feature configured to prevent the top lift from rotating. The heel assembly includes a threaded insert, a spring, a hollow insert, and a second wedge-lock feature. The threaded insert is received inside an opening formed in the heel to receive the threaded portion of the rigid shaft member. The spring is also received inside the opening and abuts against the threaded insert. The hollow insert abuts against the spring. The rigid shaft member passes through the threaded insert, the spring, and the hollow insert. The second wedge-lock feature locks with the first wedge-lock feature to retain the top lift on the end of the heel. A cutout feature in the heel tip cooperates with the shaft member to lock the two together and allow the heel tip to be replaced without removing the shaft member.

A heel insert is provided for an article of footwear that includes an upper defining a foot-receiving cavity having an ankle opening. The heel insert includes a base. The heel insert includes a spine extending outward from the base to a tip of the spine such that the spine extends upward along a posterior wall of a heel region of the upper toward the ankle opening when the base is operatively connected to the heel region. The tip of the spine is moveable relative to the base between a first position and a second position along a longitudinal axis of the article of footwear. The heel insert includes a spring operatively connected to the spine such that the spring biases the tip of the spine toward the first position of the tip. The tip of the spine is resiliently deflectable toward the second position against the bias of the spring.

A heel support is provided for an article of footwear that includes an upper defining a foot-receiving cavity having an ankle opening. The heel support includes a cradle configured to be operatively connected to a heel region of the upper. The cradle includes a base and a cradle arm extending outward from the base to a tip portion such that the cradle arm extends upward toward the ankle opening and toward a posterior wall of the heel region. The tip portion is moveable relative to the base between an expanded position and a collapsed position. The heel support includes a metallic spring operatively connected to the cradle such that the spring biases the tip portion of the cradle arm toward the expanded position of the tip portion. The tip portion of the cradle arm is resiliently deflectable toward the collapsed position against the bias of the spring.

A spring compression system for shoes that functions much like a car's suspension in absorbing the shock and impact that occurs when shoes contact the ground. Wherein form is the most important element of shoes and function is a distant afterthought, the ergonomically poor design of shoes desperately require the healthier environment for the wearer a spring compression system would offer with the additional ability to be adjusted to suit the weight of the wearer as well as the level of shock absorption desired.

A shoe configured to adjust from a first configuration having a first height to a second configuration having a second height includes a sole. Sole includes a toebox, a shank, and a seat. The shank is rotatably connected to the toebox and the seat. The shoe also includes a heel assembly mounted to the seat. The heel assembly includes a collapsible exterior shell that adjusts the shoe between the first configuration and the second configuration, the first height of the first configuration being greater than the second height of the second configuration.

A shock-absorbing shoe using a spring, comprising: a spring for absorbing shock by providing an elastic force; an outsole which constitutes the bottommost sole of a shoe; an upper sole which is fixed to the top of the outsole, has a gap between the heel part thereof and the heel part of the outsole so as to provide a space in which the spring is provided, and is lowed by the weight of a user or raised by the elastic force of the spring; a lower spring seat which is formed on the upper surface of the outsole and supports the lower end part of the spring; an upper spring seat which is formed below the bottom of the upper sole and supports the upper end part of the spring; and a raising and lowering guide for guiding the lowering and raising of the upper sole straightly.
