A walking-assisted air-jet insole includes an insole base. A plurality of pressed-air outlet units that can generate airflow based on stepping pressure are provided on the insole base; the pressed-air outlet unit includes a cavity for retaining air. An upper part of the insole base is provided with an upper air hole that communicates with the cavity, and a lower part of the insole base is provided with an air sac part that is elastically deformed and restored based on the stepping pressure. A volume of the cavity can be changed based on the elastic deformation and restoration of the air sac part. A lower end of the air sac part is provided with a convex column that moves up and down based on the stepping pressure. The cavity includes an upper cavity portion and a lower cavity portion from top to bottom.

A footbed system (10) for footwear comprises an insole mechanism (14), a midsole mechanism (11), wherein the insole mechanism is positioned on the midsole mechanism, and the outsole mechanism (15) is positioned under the midsole mechanism. The insole mechanism comprises a footbed insole (1), a heel pad (2) and a forefoot pad (3). The footbed insole comprises a pad anatomically shaped to correspond to the sole of a human foot, wherein the heel pad is positioned in the hindfoot portion of the footbed insole, and the forefoot pad is positioned in the forefoot portion of the footbed insole. The outsole mechanism comprises an opening (15A) for exposing a natural gait line groove of the midsole mechanism.

A weight adjustable orthotic insert system includes an orthotic insert and a weight adjusting leaf. The orthotic insert corrects joint misalignment of a user based on a weight plus any additional load, foot flexibility or activity level (e.g., momentum) of the user. The weight adjusting leaf may be attached to the orthotic insert when the user is carrying a payload over a distance (e.g., a heavy pack or body armor) so that the orthotic insert provides the proper degree of correction given the increased weight instead of being collapsed by the additional weight.

A pressure unloading device for unloading pressure on a pathological prominence of the foot includes a securement and a spacer. The securement wraps around a portion of a foot and secures a spacer to a region of the foot proximate to a pathological prominence in order to unload pressure on the prominence. Pressure unloading devices can further include footwear, such as a shoe or other footwear or footwear liner having voids and/or spacers.

A footwear, including an outsole including an anterior portion and a posterior portion wherein at least one of the anterior portion and the posterior portion are configured to receive at least one protuberance, the outsole including a visible outsole map including at least one of an anterior portion outsole map and a posterior portion outsole map, each including different outsole coordinate systems, and at least one protuberance movably mountable on the outsole and configured to contact the ground and including at least one visible protuberance coordinate system corresponding to the outsole map, wherein each of the reference points on the outsole map represents a unique protuberance alignment setting in respect to the outsole map.

A fiber-composite insert for footwear comprises a plurality of ribs arranged in a lattice structure, the ribs comprising a plurality of fibers in a resin-matrix.

A shoe includes: an upper in which an upper middle foot portion covering a middle foot portion of a foot of a wearer, an upper rear foot portion covering a heel portion of the foot, and a foot insertion opening for inserting the foot are formed; a sole located below the upper; a first support member disposed below a medial longitudinal arch of the foot inside the upper and including a lateral foot side portion fixed to the upper or the sole; and a first pulling-up member connected to a medial foot side portion of the first support member and enabled to apply, to the first support member, force for pulling up the first support member in a direction toward the upper rear foot portion and away from the sole.

An orthotic device for footwear. In one embodiment the orthotic device comprises a substantially planar body having a resiliently deformable outer peripheral portion, a cell frame, and an inner array of detachably coupleable cells, wherein each cell comprises one or more protuberances and/or recesses which permit the cells to detachably couple with the cell frame.
