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 sole for sports shoes is provided including a base or tread component, a top or midsole component and at least one intermediate or elastic cushioning component. Advantageously, the sole is able to provide high cushioning, elastic yield and stability thanks to the mechanical or structural characteristics of the sole.

A bimodal heel counter apt for a rapid entry and release footwear devices, that includes a flexible hollow hemisphere portion, a heel tab, a secondary heel tab, a back sole base, an anchor system, and dependent fastening elements. The bimodal heel counter and dependent fastening systems are biased to one of two stable positions, which elastically morphs by stored potential energy with applied force from one position to the other, configured to collectively snap a footwear device between an open and closed position, for donning and doffing, or securing the foot as to enable active footwear use.

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 fluid-filled chamber, which may be incorporated into articles of footwear and other products, may include an outer barrier and a tensile element. The outer barrier may have a first portion, an opposite second portion, and an interior surface defining an interior void. The tensile element may be secured to the first portion of the outer barrier in a plurality of first bond areas and may be secured to the second portion of the outer barrier in a plurality of second bond areas. Each of the bond areas may be connected to portions of the tensile element spaced from the interior surface.

A shoe includes an outsole, a shank and a heel area defined in the underside thereof The shank is connected between the outsole and the heel area. The heel area is a recessed area. A replaceable heel has a connection portion on the top thereof so as to be detachably connected to the heel area. A heel lift is defined in the underside of the replaceable heel and includes multiple anti-slip members extending therefrom. The replaceable heel is easily detached from the shoe and a new one is attached to the heel area of the shoe.

A sole for sports shoes is provided including a base or tread component, a top or midsole component and a least one intermediate or elastic cushioning component. Advantageously, the sole if able to provide high cushioning, elastic yield and stability thanks to the mechanical or structural characteristics of the sole.
