The present invention relates to a shank adapted for being integrated into a shoe sole and for mounting a heel element, wherein said shank at its heel portion is adapted to be connected to the heel element and wherein said shank comprises an upper surface pointing towards the inner shoe. At least a part of the upper surface at the heel portion is cup-shaped and adapted for receiving sole material inside the cup when integrating said shank in said sole during molding of said shoe sole. Thereby, due to the amount of sole material present in the heel portion, the sole material covers the means used for connecting the shank to the heel element. Thereby, based on the properties of the sole material, the heeled shoe becomes comfortable and flexible at the heel portion. The invention further relates to a sole for a shoe with a cup-shaped shank and more specifically to a shoe with a cup-shaped shank.

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 foot arch support device includes a base seat, a movable unit, high and low heel members, and an actuating unit. The base seat includes a first base plate. The movable unit includes a movable plate that is movable relative to the first base plate between high and low curvature positions. When the low heel member is coupled to the base seat, the movable plate is at the low curvature position. When the high heel member is coupled to the base seat, a support part of the high heel member abuts against the movable plate, and the movable plate is pushed by the high heel member to the high curvature position. The actuating unit is operable for permitting removal of a selected one of the high and low heel members from the base seat.

A shoe system has an interchangeable upper. The shoe includes a shank (6); a heel (9); and a platform (8). The shank is assembled to the heel. A fastener (37) joins the shank (6) and the platform (8). The shank (6) and the platform (8) are configured to removably assemble to each other. The shank (6) and the platform (8) are removably joined together by the fastener (37).

A removable heel connector apparatus comprises a shoe, a heel connector, a heel, a heel release. The heel connector includes a bolt to connect the heel against withdrawal from the shoe. The heel may be withdrawn from the shoe by depressing the heel release. The heel connector also includes a torque balance providing strength and durability in use to a shoe with removable heel as if an ordinary shoe without removable heel.
