The present disclosure provides a footwear technology system including a multilayer shoe sole system. The multilayer shoe sole insert can include a lower outsole layer, a midsole layer, and an upper insole layer, wherein the midsole layer includes a plurality of pins extending from the bottom surface of the midsole layer, wherein the pins engage with the pin holes in the outsole layer. The system can include a dynamic upper foot retention system that moves in harmony with the foot's optimal natural movement. The dynamic upper foot retention system can include a top component connecting the lace area to the sole system, and back component that connects the upper heel area to the sole system, wherein when the laces are tightened, the force is directed towards the heel securing the foot to the shoe without forcing the arch down or constricting the raising of the foot arch.

An insole assembly is provided comprising an insole having an upper surface upon which an underside of a foot may contact and be supported. The insole assembly has at least one protrusion which projects away from the upper surface of the insole. At least one of the protrusions is detachably connected to the insole. The protrusions may be interchanged to customize an insole assembly to provide enhanced cutaneous stimulation of targeted regions of a foot.

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.

The present invention regards a sole for a sport shoe, work shoe or leisure shoe including a main body having a lower layer delimiting a surface, lower during use, set to come into contact with the ground and an upper layer set to come into contact with a foot of a user or to support from the bottom, during use, an insole.

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.

A therapeutic safety shoe assembly for reducing foot fatigue includes a shoe that is wearable on a user's foot. The shoe has a sole, a heel and a toe, and a shield is integrated into the toe to protect the user's toes. A vibration unit is provided and the vibration unit is integrated into the shoe. The vibration unit vibrates the shoe when the vibration unit is turned on to massage the user's foot when the shoe is being worn. The vibration unit includes a heel element that is integrated into the heel of the shoe and the vibration unit includes a sole element that is integrated into the sole of the shoe.

A tactile feedback shoe sole for footwear comprising a main body that defines a toe portion, a middle portion and a heel portion. A first chamber filled with a fluid is disposed in one or more areas of the main body. A second chamber comprising a second chamber upper wall, a second chamber lower wall and projections is disposed in the arch region of the middle portion. Channels disposed between the first and the second chambers help in establishing fluidic communication between the first and second chambers. If the second chamber is compressed before the first chamber getting compressed, which is likely to happen when the feet of the user of the sole overpronate, the second chamber upper wall comes in contact with the second chamber lower wall and the projections are felt by the user in the arch region since the second chamber is not filled with the fluid.

A shoe accessory of a shoe adaptive for activating a bottom of a foot wearing the shoe is provided. The bottom of the foot has a forefoot, a heel, and an arch between the forefoot and the heel. The shoe accessory includes a main body and a plurality of stimulating elements mounted to the main body. Each of the stimulating elements is movable universally on the main body and is adapted to exert a pressing force on a non-fixed point of the bottom of the foot to stimulate the arch.

A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer, and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.
