An article of footwear includes a midsole component and a seamless braided upper having a bottom peripheral portion connected to the midsole component. The seamless braided upper extends from a forefoot region to a heel region and from a lateral side to a medial side of the article of footwear. The bottom peripheral portion defines a bottom opening in the seamless braided upper, wherein the bottom peripheral portion extends along the forefoot region, the lateral side, the heel region, and the medial side of the article of footwear.

In a method and device for extracting joint line of shoe, a contact end of a contouring tool is provided to contact a joint contour of a shoe sample, an encoder is provided to generate a plurality of first trajectory coordinate signals of the contact end while the contact end is moved along the joint contour, and a signal processor is provided to receive the first trajectory coordinate signals to create a digital joint line.

Foam items may be buffed using particles such as particulate sodium bicarbonate in accordance with the present invention. Foam items may be, for example, expanded EVA foam items pre-formed into an intermediate size and shape. A skin layer may be formed during the expansion of the foam item to form an expanded foam item which may be entirely or partially removed by buffing the item using particles projected with selected buffing parameters. The buffing parameters may be varied based upon the thickness of at least a portion of the skin layer and/or the desired degree of moldability for the foam item after buffing. Particulate sodium bicarbonate or other types of particles used for buffing may be recycled and reused for further buffing of foam items.

The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.

A segmented sole for an article of footwear comprises a forefoot region, a heel region, and a segmentation zone disposed between the forefoot and heel region. The segmentation zone includes a plurality of segments separated from each other and from the forefoot and heel by a plurality of sipes, cuts, or gaps. The segmented sole produces bending along a segmentation axis disposed along an arch of a wearer of an article of footwear including the sole, allowing for arch support and natural foot movement.

A method of making an article of footwear with a braided upper is disclosed. The method includes overbraiding a last to form a braided upper and cutting a bottom opening in the braided upper to remove the last. The bottom opening is cut so as to leave a bottom peripheral portion on the bottom side of the braided upper. A midsole is attached directly to the bottom peripheral portion using a bonding agent.
