A molded insole includes a base, an internal lateral arch that is provided to accommodate the arch of the foot and that is raised relative to the base, and at least one hard region that is integrated into the base, having a hardness equal to or greater than that of the base. The base and the internal lateral arch of the insole constitute a single, mono-material part.

A bladder for an article of footwear includes a chamber having (i) an arcuate segment extending from a first transition to a second transition, (ii) a first plurality of elongate segments extending in a first direction from the first transition to a first terminal end, and (iii) a second plurality of elongate segments spaced apart from the first plurality of elongate segments and extending in the first direction from the second transition to a second terminal end. The bladder also includes a web area connecting the arcuate segment, the first plurality of elongate segments, and the second plurality of elongate segments and extending to a terminal edge spaced apart from each of the first terminal end and the second terminal end.

Disclosed herein are insoles useful for treating skin injuries on a foot, for instance ulcers. The insoles are customizable for each patient's foot and can include various portions of differing softness, depending on the needs of the patient. For instance, it can be beneficial for certain sections of the foot to contact a firmer material, whereas other sections contact a softer material. Some, or all, of the materials can include one or more biofidelic skin simulant materials. Thus, various implementations include one or more regions that can include the same or different materials. For example, a custom insole can include a heel support region, a midfoot support region, and a forefoot support region, and the support regions can be subdivided into medial and lateral support regions or toe regions. One or more regions may have a custom isolation segment to prevent the progression of ulcers and/or expedite wound healing.

A sole structure for an article of footwear having a heel region, a mid-foot region, a forefoot region, an interior region, and a peripheral region. The sole structure including a bladder having a chamber including an arcuate segment extending around the heel region, a first segment extending along the peripheral region on a medial side of the sole structure from the arcuate segment to a first terminal end in the forefoot region, and a second segment spaced apart from the first segment across a width of the sole structure and extending along the peripheral region on a lateral side of the sole structure from the arcuate segment to a second terminal end in the forefoot region. A peripheral outsole extends along the chamber and a first cushion is disposed between the first segment and the second segment and is exposed through an opening of the peripheral outsole.

An article of footwear has an upper that is direct attached with the sole. The direct attach sole has an insert, such as an airbag, that forms a portion of a sidewall. The insert is externally visible and forms at least a portion of an external sidewall of the sole. The insert is formed into the direct attach sole by having the insert or a mask temporarily joined with the insert contact a sidewall molding surface of a mold used in the direct attach operation such that the insert results in forming a visible element of the direct attached sole.

Methods, systems, and non-transitory computer readable medium for foot differentiation scoring pertaining to an individual's differences in their two feet. A method includes receiving, from sensors of a scanning device, pressure and/or other measurement data corresponding to feet of a user. The method further includes preprocessing the pressure and/or measurement data. The method further includes generating, based on the preprocessed pressure and/or measurement data, a foot differentiation score based on differences between a left foot and a right foot of the user. The foot differentiation score may assign or correspond to a numerical rating based on how different the user's left foot and right foot are from each other.

To provide footwear, in which a cushion layer is effectively bent even though an outsole of footwear has a thick cushion layer to distribute weight, thereby putting no stain on movement during walking, the footwear according to the disclosure includes uppers provided to surround at least a certain region of a wearer's foot; a supporter disposed below the uppers and supporting the foot; and a walking assister provided in the supporter, adjacent to a metatarsophalangeal joint area of the foot, and generating elasticity in a walking direction of the wearer.

A trim to fit insole for insertion into a shoe has a raised metatarsal pad on the insole upper surface, wherein the raised metatarsal pad has a first region rising at a slope inboard from a medial edge of the insole board, and configured to underlie the first metatarsal head of the wearer, a second, raised top surface region configured to underlie the second to fourth metatarsal shafts of the wearer, and a third region sloping downward towards the lateral edge of the insole configured to underlie the fifth metatarsal shaft of the wearer, wherein all three regions cooperate to evert the first metatarsal and to invert the fifth metatarsal of the wearer.

The article of footwear may include an upper, a heel region having a heel core and a heel perimeter, a forefront region, a medial side, a lateral side, an outsole and a midsole. The midsole may be a dual durometer midsole and include a soft durometer positioned between the heel region and the forefoot region and a firm durometer positioned around the heel perimeter.
