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 sole structure for an article of footwear includes a midsole coupled to an outsole. The midsole includes a plurality of sipes on a first side and a plurality of sipes on a second side opposite the first side. The sipes partition portions of the midsole body into impact attenuation cells on the first and second sides of the midsole. The second side of the midsole further includes a plurality of grooves and a plurality of protruding members separated by the grooves. The protruding members extend from a midsole body towards the outsole when the midsole is coupled to the outsole, spacing the midsole body apart from the outsole.

The invention relates to a set comprising a shoe (1) with a shoe sole (3), which has a support layer (31) and a plurality of support elements (4), wherein the support layer (31) comprises a plurality of cavities (310) having identical, constant cavity cross-sectional areas. At least one end face of each cavity (310) is recessed, whereby a structure of cavities (310) open on at least one side is created in the support layer (31). The support elements (4) are designed as rods with identical, constant cross-sectional areas and can be inserted into and removed from the cavities (310) in a form-fitting manner, wherein the support elements (4) are present in different strengths, such that the damping of the shoe sole (3) can be changed by the choice of the inserted support elements (4).

A invention disclosed a bio-mimicked three-dimensional laminated structure at least comprising a flexible lattice structure, which is characterized in that the flexible lattice structure comprises a plurality of particle units are uniformly disposed and evenly distributed in the X-axis, the Y-axis, and the Z-axis direction and evenly distributed as a lattice matrix of an array grid in an identical plane; wherein each of the particle units is an opened hollow shell or a close shell. The design eliminates the need for support structures and the subsequent post-processing required to remove them. A shell-shaped close cell bio-mimicked three-dimensional laminated structure bio-mimicking a sea urchin shape was introduced for the load-bearing structure application.

Methods for preparing a footwear article are disclosed herein. An example method may comprise disposing resin adjacent a mold, disposing a lattice structure in at least a portion of the resin disposed adjacent the mold, closing the mold using a lasted upper, injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

Ground-engaging components for articles of footwear include an upper-facing surface and a ground-facing surface opposite the upper-facing surface. At least the ground-facing surface may be formed to include a matrix structure, and this matrix structure may include a plurality of open cells (e.g., in a heel region and/or an arch region) and a forefoot region including a plurality of closed forefoot support cells. The ground-engaging component may be engaged with a midsole member (e.g., including a foam midsole element and/or one or more fluid-filled bladders), and this combination may form a sole structure that is engaged with an upper to form an article of footwear.

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.

Articles comprising one or more additively-manufactured components are provided, as are method of additively manufacturing such components. The additively-manufactured components are designed to enhance performance and use of the article, such as, but not limited to: impact protection, including for managing different types of impacts; fit and comfort; adjustability; and/or other aspects of the article. The provided methods of additive manufacturing include methods involving expandable materials and the expansion of post-additively manufactured expandable components.

A footwear cover that includes a sole portion that includes an inner layer and an outer layer that cooperate to define at least a first interior space therebetween, at least a first bladder member disposed in the first interior space, and an upper connected to the sole portion. The first bladder member defines a bladder interior that includes a non-Newtonian fluid disposed therein. The upper includes at least a first securement strap for securing the footwear cover in a closed position.

An article of apparel includes a composite material. The composite material includes a pliable first layer and a resilient second layer, where the first and second layers are secured to each other via a patterned strand network. In forming the composite material, the second layer is stretched and maintained under tension while the first layer is secured to the second layer via the patterned strand network. The tension on the second layer is then released, resulting in contraction of the second layer in relation to the first layer and an outward buckling or protrusion of the first layer in relation to the second layer to form protruding cells along the composite material that are bounded by portions of the patterned strand network. The patterned strand network can be formed using embroidery with one or more auxetic patterns in the stitching.
