A method of forming an upper for an article of footwear includes providing a first material layer over a shoe last, providing a second material layer over the first material layer such that the first and second material layers adhere to each other at an interface between the first and second material layers, where one or both of the first material layer and second material layer is provided by spray forming a polymer material onto the last. The material layers are removed from the last and turned inside out such that the first material layer includes an exposed surface that forms an exterior surface of the upper.

Disclosed is a waterproof shoe with an improved ventilation mechanism, designed to circulate air from the outside environment through the shoe in order to provide convective cooling to a wearer's foot. In a desired embodiment, the shoe may incorporate a pump-ventilation mechanism which, coupled with airflow channels incorporated in the upper, acts to establish continuous substantially one-way airflow through the shoe in a heel-to-toe direction while a user walks.

The shoe 100 includes the outer sole 10 brought in contact with the road surface, the midsole 20 arranged on the outer sole 10, and the upper 9 covering the foot from the upper side. The midsole 20 includes at the middle foot portion the cut-out portion 21 and the like opened to the outside and closed at the middle portion in the width direction.

An upper for a sports shoe may include a component such as a vamp or a rear portion. The shoe component may include a UV curable microlattice structure with a plurality of regions such that each region has a different density. In some cases, the microlattice structure may include a high density microlattice structure, a mid-level density microlattice structure, and a non-structural region with a low density microlattice structure.

The present invention generally relates to soles in particular midsoles for sports shoes. According to an aspect, an additively manufactured sole is provided. The sole comprises a lattice structure, the lattice structure comprising a plurality of cell elements. The sole further comprises a heel element, three-dimensionally encompassing the heel. Moreover, the sole comprises a base portion interconnecting the heel element and the lattice structure, wherein the base portion has an extension arranged to connect to a plurality of adjacent cell elements, wherein the plurality of adjacent cell elements is not positioned along an edge of the lattice structure.

The invention is an article of footwear comprising a waterproof upper (30) material having a breathability of less than 3 mg/cm<2>/h according to ISO (11092, 14268) 14268 (2012). The upper (30) material comprising at least one vent having a vent assembly (31) disposed within the at least one vent. The vent assembly (31) further comprises a waterproof, water vapor permeable functional layer (38) and a plurality of slats (32) disposed adjacent to the functional layer (38) and spaced apart from each other and from the functional layer (38) to provide for water-vapor flow through the vent assembly (31).

A ventilation sole for footwear, the sole including: a communicating vent-hole through which the inside and outside of footwear communicate with each other to allow air to flow; and a valve selectively opening and closing the communicating vent-hole, wherein the valve includes: a housing module configured to have opposite ends being open such that a channel is provided therein to communicate with the communicating vent-hole; an open-close module configured with a first closing surface and a first through-hole; and a rotation module configured with a second closing surface and a second through-hole, and rotating to move a position of the second through-hole. Accordingly, a wearer can easily open and close the valve by rotating the rotation module according to the intention of the wearer, whereby air inside and outside the footwear can be circulated selectively and optimal foot conditions can be improved.

A sensor system is adapted for use with an article of footwear and includes an insert member including a first layer and a second layer, a port connected to the insert and configured for communication with an electronic module, a plurality of force and/or pressure sensors on the insert member, and a plurality of leads connecting the sensors to the port.

Computer based systems and methods for designing (e.g., customization) of consumer products, articles of footwear, knit footwear uppers, and the like. In some embodiments, a user may generate and/or modify footwear designs using a footwear design interface. Additionally or alternatively, the footwear design interface may be configured to simulate the layout and/or operation of a knitting machine to provide the user with the impression of physically designing and/or manufacturing an article of footwear. In other embodiments, the system may disallow prospective footwear design changes based on limitations associated with inventory availability and the footwear design characteristics.
