An article of footwear is disclosed that includes a sole structure having a bladder element. The bladder element includes multiple fluid-filled tubes that are substantially decoupled from one another along their respective lengths. The tubes extend lengthwise at least partially from a lateral extremity of the sole structure to a medial extremity of the sole structure. A method of manufacturing a sole structure of an article of footwear includes forming a bladder element with multiple tubes substantially decoupled from one another along their respective lengths. The method includes positioning the bladder element so that the tubes extend lengthwise at least partially from a lateral extremity of the sole structure to a medial extremity of the sole structure.

The present invention provides a shoe material part mainly composed of a coffee ground material, a porous material and a rubber-plastic material, and is made of a recycled waste porous material and recycled waste coffee grounds, which can improve the value of waste recycling and reuse, and reduce environmental pollution, in addition to reducing waste, there will be no residue pollution of natural ecology and other issues in the subsequent environmental recycling, quite in line with environmental requirements. In addition, the present invention has the function of natural deodorization, because the coffee grounds can naturally diffuse the aroma of coffee, and the characteristics of better deodorization and air permeability of the coffee grounds can be used to reduce the foul smell of a user's foot.

An upper for an article of footwear is configured to be connected to a sole structure and is configured to receive a foot. The upper includes a knitted component having a strobel portion that is configured to be disposed underneath the foot. The strobel portion defines an interior surface and an exterior surface of the knitted component. The strobel portion defines a strobel passage between the interior surface and the exterior surface. Also, the upper includes a tensile strand that extends through the strobel passage.

A separable footwear article may comprise an outsole oriented at the bottom of the footwear and configured for ground contact, the outsole comprising a first material; an upper portion releasably coupled to the outsole with thread using chain stitching, the upper portion comprising a second material different from the first material; and an insole removeably disposed adjacent the upper portion and the outsole, the insole comprising a third material different from the first material and the second material; wherein the outsole, the upper portion, and insole are capable of being separated by releasing the thread and hand pulling the thread from the footwear article.

Articles of footwear and methods of making articles of footwear including one or more continuous threads wound around anchor points. The winding of the one or more continuous threads forms a thread pattern that imparts desired characteristics to components of the article of footwear. Thread lines of the thread pattern may be bonded together. In some embodiments, thread lines may be bonded with a bonding layer.

A shoe insole includes a semi-rigid shell for providing a wearer with extended comfort. The semi-rigid shell includes a notch which is located on the outward side of the wearer's foot and accommodates pronation of the foot during use. Additionally, the semi-rigid shell includes an extended side portion which is located opposite of the notch side on an inner side of the wearer's foot. The semi-rigid shell is shorter in length than the length of a shoe sole and slightly shorter in width and may be combined with an insole comfort cover to provide cushion between the wearer's foot and the semi-rigid shell.

The present invention relates to a process for producing a flexible polyurethane foam thermally recyclable by fusion, and to hybrid materials made of flexible polyurethane foam and compact thermoplastic elastomer and/or expanded thermoplastic polyurethane.

Process for obtaining ecological footwear using recycled or waste organic materials for the production thereof, particularly materials such as sargassum, coffee waste, and agave bagasse and using solvent-free water-based adhesives, therefore friendly to atmosphere. The process includes assembling the footwear with woven fabrics and non-woven polyester fabrics obtained from fibers that are produced with bottle flakes and postindustrial recycled material of the same polymer, in addition to including the thread and laces made with filaments obtained from the same recycled nature, and incorporating the sole and details with a percentage of recycled polyester plastic bottles, sargassum, coffee waste, and pulverized agave gabazo used as an inert load, so the footwear presented has a recycled polyester content, Sargassum, coffee residues and agave gabazo between 5 and 90% in weigh.

A shoe may include an upper portion constructed from a continuous textile (e.g., a knit textile) that includes multiple regions having different textile properties to improve the performance of the shoe, including durability and comfort. In some cases, the multi-region upper portion may include regions having different thickness and/or flexibility based on a location relative to a wearer's foot to better support the wearer's foot. For example, the multi-region upper portion may include a reinforcement region having a first thickness and a flex region having a second thickness less than the first thickness. As another example, the multi-region upper portion may include a reinforcement region having a first stiffness and a flex region having a second stiffness less than the first stiffness.

A shoe insole includes a semi-rigid shell for providing a wearer with extended comfort. The semi-rigid shell includes a notch which is located on the outward side of the wearer's foot and accommodates pronation of the foot during use. Additionally, the semi-rigid shell includes an extended side portion which is located opposite of the notch side on an inner side of the wearer's foot. The semi-rigid shell is shorter in length than the length of a shoe sole and slightly shorter in width and may be combined with an insole comfort cover to provide cushion between the wearer's foot and the semi-rigid shell.
