The present invention relates to a shoe, for example a sports shoe, such as a cycling shoe including a sole, an upper constrained to the sole and an insole inserted in the upper or constrained to the open bottom of the upper.

The present disclosure provides an item of footwear with removable modular sole member that allow customization of the footwear with respect to traction, cushioning, support, fit, performance and/or aesthetic functions and features. It is an object of the present invention to provide a footwear which can be customized to be utilized for varying conditions and/or occasions. Another object of the invention is to provide a footwear with relatively simple means for quickly and firmly securing an interchangeable sole with effective elements which do not adversely affect the appearance or comfort of the footwear.

An article of footwear may include an upper configured to receive a foot of a wearer and a sole structure fixedly attached to the upper, the sole structure including a ground-contacting outer member and a removable midsole. The footwear may further include a motorized tensioning system including a power source, a control unit, a tensile member, and a motorized tightening device, the motorized tightening device being attached to an outer surface of the upper, and the tightening device being configured to apply tension in the tensile member to adjust the size of an internal void defined by the article of footwear. In addition, the power source and the control unit of the tensioning system may be configured to be removably disposed in the removable midsole.

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.

The invention relates to a method for producing a shoe (1), in particular a sports shoe. In order to be able to produce the shoe economically and in the process to achieve a particularly good wearing comfort, the invention provides the steps of: a) Producing a shoe upper (2), wherein the shoe upper (2) has an upper region (3) that covers the upper region of the wearer's foot and a lower region (4) that encloses the sole of the wearer's foot; b) Producing a sole part (5), wherein the sole part (5) has a bottom region (6) and a lateral wall region (7), wherein the bottom region (6) and the wall region (7) delimit an upwardly open receiving space (8) for bulk material (9); c) Filling the receiving space (8) with a bulk material (9), wherein the bulk material consists at least in part, preferably entirely, of a thermoplastic elastomer (TPE); d) Fastening the shoe upper (2) to the sole part (5) such that the lower region (4) of the shoe upper (2) comes to rest on the bulk material (9).

A method for assembling shoe components includes the steps of: providing at least two shoe components, a shoe last and a film unit; placing the at least two shoe components on an outer surface of the shoe last; removably covering an assembly of the at least two shoe components and the shoe last with the film unit such that the film unit and the shoe last cooperatively define a confining space therebetween; and pumping air out of the confining space and heating the at least two shoe components to shrink and deform the film unit so as to press the at least two shoe components to adhere tightly to each other.
