Boot shafts can be designed for comfort by providing expansion in the shaft of a boot. Portions of a shaft can be replaced, augmented, or associated with a more deformable and elastically resilient material or materials. When effectively associated or integrated, the elastic material can allow for temporary expansion of the shaft to ease passage of the heel and foot through the shaft and into the shoe box. A long thin resilient feature can provide expansion and ease of passage of a foot down the boot shaft while also potentially minimizing conspicuous departure from conventional stylings. Such features can also be physically obscured with straps (which may rotate, for example). Such features may be curved or angled to visually in fit with and even be camouflaged by surrounding decorative ornamentation on the shaft of such a boot.

A shoe including a sole and an upper. The upper is coupled to the sole. The upper includes an outer layer and an inner layer. The outer layer has an outer surface and an inner surface. The inner surface of the outer layer is in direct contact with the inner layer. The outer layer is a hot melt thermoplastic material, and the inner layer is a material different from that of the outer layer. At least a portion of the outer layer is adhered to the inner layer, and the inner layer including a portion not covered by the outer layer.

The present invention relates to an upper for a shoe, including an inner layer; an outer layer overlapping the inner layer at least partially; wherein the outer layer includes a plurality of cuts; wherein the inner layer includes a plurality of protrusions; wherein each cut at least partially overlaps at least one protrusion; wherein each protrusion causes an extension in width of its corresponding cut when the shoe is worn.

A three-dimensional flexing resistance waterproof and moisture-permeable shoe upper, including fabric, waterproof and moisture-permeable membrane, and eco-friendly adhesive is provided. The waterproof and moisture-permeable membrane is closely bonded with an inner layer of the fabric. The outer layer and inner layer of the fabric are closely bonded together through eco-friendly adhesive, which is bonded with the fabric in a mesh structure. The eco-friendly adhesive includes liquid adhesive or powder adhesive. The shoe upper is shaped by the heating method which includes vacuum heating, electric heating or steam heating. The outer layer of the fabric is closely bonded with the inner layer, so that the defects of the accumulation of sludge, dust and water droplets between the outer layer and the inner layer of the existing shoe upper is overcome, making the shoe upper waterproof and moisture permeable. The three-dimensional shoe upper is formed through vacuum forming method.

An outsole for an athletic shoe that includes a heel section and a forefoot section. The heel and forefoot sections are on the outer surface of the outsole. The forefoot section includes a tread pattern that provides first and second ground friction forces. The first ground friction force promotes rotation in a first rotational direction about a rotation point of the forefoot section. The second ground friction force restricts rotation in a second rotational direction about the rotation point. The second rotational direction is opposite of the first rotational direction and the second ground friction force is greater than the first ground friction force.

A sock shoe has a single layer of base fabric having a volumetric configuration for receiving at least a forefoot portion of a user's foot. The sock shoe is configured with an upper portion for receiving a top portion of the user's foot and a bottom portion for receiving a bottom portion of the user's foot. The base fabric has a knit or woven structure that is resiliently elastic. An elastomeric coating is fused to the base fabric in a single-layer unitary structure to provide at least two of: (i) a retention function, (ii) a durability/foot protection function, (iii) a grip or anti-slip function, and (iv) an outsole function. The bottom portion having an outer-facing, ground-contacting surface and an inner-facing, foot-contacting surface, the ground-contacting surface including at least one outsole portion being formed of the fused elastomeric material, and the inner-facing, foot-contacting surface being formed of the fused elastomeric material.

A manufacturing process involving a series of discrete operations can be modified by adding, removing, or reordering operations, without design changes to the equipment. The manufacturing process uses a frame comprising one or more alignment tabs. Each alignment tab comprises an alignment element. The alignment element interacts with a corresponding alignment element at a manufacturing station to identify to the manufacturing station the position and orientation of the frame. The frame supports a material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the pliable material on the frame from the interaction of the alignment elements on the frame and the manufacturing station. The operations at any particular manufacturing station can therefore be positioned independent of what operations, if any, have come before, or in what order.

An article of footwear includes an upper defining a foot-receiving cavity with a heel region, and a heel support device extending around the rear of a heel region from a lateral side to a medial side. The heel support device may include a plurality of slats and a base, the plurality of slats providing a progressive gradient of lengths and/or widths, and/or one or more pegs extending from the device for attachment to a footwear upper, and/or an elongated tip that may be disposed in a cavity of an extension of a heel collar of the upper.

An article of footwear and a method of manufacturing the same is provided. The article comprises an upper having an inner layer and an outer layer coupled to the inner layer, such that the inner layer and the outer layer define a closed pocket therebetween. An insert is disposed in the closed pocket. The outer layer is formed of an at least partially transparent material, such that the insert is at least partially visible through the outer layer. The method comprises placing the insert in a recess defined by the outer layer of the upper, such that the insert abuts an inner surface of the outer layer and positioning the inner layer on the inner surface of the outer layer over the recess and the insert, such that the inner layer and outer layer form the closed pocket at the recess with the insert disposed within the closed pocket.

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.
