A shoe includes an outsole having a room defined in the top thereof. A vamp is connected to the peripheral wall of the room. An air pad and an insole are located in the room. The air pad includes a front pad and a rear pad. A tube is connected between the front and rear pads. The front pad includes an inflatable support portion and a resilient support section which is located at the front portion of the front pad. The resilient support section has multiple buffering portions. A plate is located on the front pad and between the inflatable support portion and the insole. The plate restricts the deformation area on the inflatable support portion to deform the insole.

A shoe having a bio foot pad, including a plurality of circumferential elastic fibers surrounded by a viscoelastic material; wherein said fibers impart a biphasic characteristic to said viscoelastic material; and wherein said fibers under compression develop a plurality of hoop stresses to facilitate load conversion and distribution of axial forces exerted against a heel area of a user.

A dress shoe includes a flexible upper structure with stretchy lining and outside layers and a zonal-structured cloth layer therebetween to enable elasticity while maintaining structure; a cushioned insole with a three-point support system under the toe crest, the arch, and the heel; and a mixed material insole and outsole to prevent slipping during walking and standing.

Systems and methods are disclosed including a tri-layer orthotic system having a heel portion and a forefoot portion to support respective heel and forefoot portions of a foot through at least a portion of a gait cycle. The tri-layer orthotic system can include an upper layer suspended over a mid-layer and a base layer to create a rear spring section, a mid-spring section, and a front spring section. A distal toe portion of the mid-layer can form the forefoot portion of the tri-layer orthotic system and a heel upper layer portion of the upper layer can form the heel portion of tri-layer orthotic system.

A shoe-pad, shoe and hallux orthotic device, the shoe-pad is configured for correcting and preventing deformity of a hallux, the shoe-pad includes a shoe-pad body, a first orthotic portion, and a second orthotic portion; the first orthotic portion and the second orthotic portion are protruded from a surface of the shoe-pad body and spaced from each other, and the first orthotic portion and the second orthotic portion are staggered from each other in a front-back direction. The first orthotic portion and the second orthotic portion are spaced from each other on the shoe-pad body, and the first orthotic portion and the second orthotic portion are staggered from each other in a front-back direction, the structure is simple, the production and using are convenient, the hallux valgus can be corrected and prevented without a surgery, and the suffering and financial burden of the patients are reduced.

The present invention relates generally to a device for supporting the foot and more particularly to a device for relieving pressure from specific areas of the foot, and for relaxing and shortening the musculatures of the foot by raising the arch. Through specific shapes and materials, the design intends to aid in alignment, add comfort, and prevent and relieve many foot problems and other lower extremity ailments. The device is uniquely designed to sit in the midfoot region of an article of footwear to relieve pressure from the heel and forefoot, redistribute pressure more evenly across the foot, and support the foot arches. The device may be constructed from flexible material which allows the orthotic to form to the shape of the shoe it is placed in. The medial wing portion of the orthotic device may utilize the medial wall of a shoe to increase arch support.

The shoe herein, in the form of a sandal, uses a combination of a midsole of varying thickness and nodules of varying diameters and heights to provide the requisite level of flexibility, support, and stimulation to the various regions of the foot. The walking action of the user creates waves of pressure across the foot, enhanced by the nodules, thereby increasing blood flow.

Gradients of pressure that generate variations in the laminar flow of the foot bed lead to better circulation and perfusion of the capillary foot bed of the foot transection irrigation, allowing for better circulation and venous return.

A sophisticated air bladder that functions as an arch support of the foot that can be adjusted, a multitude of times as needed, by the user. The bladder is constructed so the air that provides the support is directed and corralled to the areas of the foot where support is typically needed and desired and will be maintained throughout weight bearing activities of the user. It is also versatile and can be used with any type of footwear, insole, orthotic or just a strap.

A sole includes a sole body supporting an entire planta of a wearer, lower protrusions protruding downward from a lower portion of the sole body toward the ground and spaced from each other, and upper protrusions protruding upward from an upper portion of the sole body toward a planta of a wearer, each of the upper protrusions being on the sole body and overlapping with an associated one of the lower protrusions. Each of the lower protrusions has, at its lower portion, a first region which makes contact with the ground, and each of the upper protrusions has, at its upper portion, a second region which makes contact with the planta of the wearer and is smaller than the first region.
