A method for producing of a foot part for a sports shoe includes the steps of producing a flexible forming part for the shoe collar and shoe sole of the foot part, and joining the edges of the forming part along the shoe sole and around the toe cap. In addition, a foot part for a sports shoe and a sports shoe are provided. The foot part for a sports shoe includes a flexible forming part having edges joined along shoe soles and around a toe cap. The sports shoe includes the foot part.

Custom shoes for preventing diabetes, preventing diabetic foot caused by diabetic complications and easing ulcer pain of diabetic necrosis which disperse plantar pressure and prevent impact are proposed. The shoes may prevent shoes from creasing and deforming by attaching a deformation prevention frame to an external side of a sole; and increase weights of shoes by manufacturing shoes, wherein columns with which springs are embedded are formed on the bottom, an insole with massaging protrusions formed on the top of columns is attached to the top of the sole, an inner sole made of shock absorption material is attached to the top of the insole, and an upper combined to a sock lining is installed to the top of the insole.

Ms. Rolon is slippers that massage between the toes. Piks moves up and down and spins 360 degree.

A midsole or insole device for a shoe includes a first variable stimulation mechanism positioned to interface one of the metatarsal heads and the heel and a second variable stimulation mechanism positioned to interface a lateral aspect of the foot between the fifth metatarsal head and the heel. During gait-related activities, the first variable stimulation mechanism produces stimulus of an intensity greater than the second variable stimulation mechanism. At least one of the first variable stimulation mechanism and the second variable stimulation mechanism comprises two bonded layers including a resilient stimulating upper layer and a less resilient stimulus-enhancing lower layer. The upper layer includes a plurality of holes that pass through the entirety of the upper layer, and the lower layer includes a plurality of equally spaced upwardly facing projections aligned substantially perpendicular to an upper surface of the upper layer.

An article of footwear including a sole structure attached to an upper defining an internal void configured to receive a foot of a wearer is described. The sole structure includes a sole body portion having a central ridge element located in an aperture in the sole body portion and the central ridge element is configured to contact the ground and move relative to the aperture.

A half-orthotic insert beginning at the heel and extending to the metatarsal region of the foot having raised elements that align with the fascia ligament for the purpose of providing relief of plantar fasciitis.

An article of footwear may include a sole structure fixedly attached to an upper defining an internal cavity configured to receive a foot of a wearer. The sole structure may include an exposed outer member configured to contact the ground, the exposed outer member including a first aperture, and a sensory feedback member disposed at least partially within the first aperture in the outer member, the sensory feedback member including a first end and a second end. The first end of the sensory feedback member may include a projection extending through the first aperture and configured to contact the ground. In addition, the second end of the sensory feedback member may include a plurality of flexible bristles extending through a portion of the sole structure and exposed to the internal cavity.

Sole for footwear that includes configurations that improve the cushioning in a user's tread with respect to known soles, comprising a lower layer and a side wall, the lower layer comprising a front part, a middle part and a rear part; in at least one portion of the front or rear part of the lower layer there are at least two protrusions, each arranged and extended transversely to the longitudinal axis of the sole and each of them comprising a first segment in contact with the lower tread and a second segment; between the side ends of each protrusion and the side wall there is a first separation that allows the full bending of each protrusion, the second segment being inclined with respect to the first segment; between two adjacent protrusions there is a second separation so that the second segment rests at least partly on the adjacent protrusion.

A somatosensation and proprioceptor stimulation surface configured to stimulate rapid-firing nerves in the receptive field of a user's glabrous skin. The somatorsensation and proprioceptor stimulation surface includes a plurality of protuberances disposed thereupon, each protuberance sized and spaced apart appropriately to impress the receptive field when pressed in contact with the glabrous skin of the user. Each protuberance widens from an apex toward a base whereby increased pressure applied to the surface increases an area of contact and stimulation by applying stimulation over a larger area of skin. The protuberances are spaced apart to maximize stimulation of rapid firing nerves while lessening overstimulation. The somatosensation and proprioceptor stimulation surface is rendered in the form of a mat or floor covering and alternatively as an insole for wear in a user's shoes.

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.
