A holistically improved shoe that incorporates beneficial aspects relating to a variety of interconnected elements, including comfort, sustainability, washability, ease of manufacturing, style, freedom and natural movement of the foot, as well as the sensory experience of a user. The shoe contains a removable insert that is configured to be removed and washed in between uses or as needed, such that a sock or other liner is unnecessary. The shoe further includes a footbed and an outsole that contain matching tread patterns. The matching tread patterns of the present technology allow the footbed and the outsole to move in concert by splaying during a stride in order to better absorb shock by mimicking the natural movements of the foot.

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.

An article of footwear includes an upper and an adjustable lacing system. The adjustable lacing system includes a plurality of fastener engaging elements located at the medial and lateral sides of the upper, where at least one of the medial side and the lateral side includes sets of fastener engaging elements. Each set of fastener engaging elements is distanced from another set in a direction transverse a lengthwise direction of the upper, and the fastener engaging elements are configured to engage with and retain a fastener structure that extends between the medial and lateral sides of the upper such that the fastener structure can be selectively engaged with different sets of fastener engaging elements to adjust a fit of the upper around a width of the foot disposed within the cavity.

An upper for an article of footwear and a method of manufacturing the upper for an article of footwear are disclosed. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The joined edges form a plurality of seams within the textile element, including a longitudinal seam extending on the lower region of the upper from a heel region to a forefoot region. Various warp knitting or weft knitting processes, including circular knitting, may be utilized to form the textile element.

An article of footwear comprises an upper and a sole structure secured to the upper. The upper includes a side portion that has a first material composition at an exterior surface of the side portion. The exterior surface has a first coefficient of friction. The sole structure has a second material composition at an exterior surface of the sole structure that underlies the side portion of the upper. The exterior surface of the sole structure has a second coefficient of friction. The first coefficient of friction is substantially equal to the second coefficient of friction.

A structure (2) and a removable component (10) for an article of footwear are disclosed. A structure comprises an outsole component (3) comprising resiliently deflecting diaphragm elements (6) for generation of pumping action for forcing air towards the removable component placed in a holding recess (7). The removable component comprises cavities (11) facing the outsole component and arranged to receive air from the resiliently deflecting diaphragm elements, air circulation channels (12) extending substantially laterally from the cavities for distributing air from the cavities to the air circulation channels, and sealing areas adjacent to the cavities and air circulation channels. The sealing areas are arranged to prevent air from escaping the cavities and air circulation channels when the removable component is inserted in the holding recess. Air circulation channels (12) may be provided with expanded areas (16). The expanded areas may have varying shapes and number of perforations.

The wearable vented non-pinching pet shoe device disclosed herein is intended to be worn indoors to prevent dogs from slipping on surfaces such as hardwood, laminate, linoleum, and tile. It is breathable, light-weight paw wear with a reinforced toe and nail guard that provides grip allowing dogs to get up with ease and to protect against surface scratches. The device is also ideal as a slip guard for dogs on boats to prevent slipping and allow water to flow through when swimming. The device that may also be worn outdoors to prevent a pet from injuring its paws on rough surfaces, and may also provide the pet with tactile feedback regarding its environment on all surfaces. Some features of the wearable vented non-pinching pet shoe device may include a thermoplastic composition, reusable and pliable materials, vent holes or perforations for breathability, airflow, and water flow, and an adjustable safety strap for easy wearability and comfort.
