An orthopedic insole is provided with an insole having a bottom portion for facing a sole of a shoe; one or more orthopedic pads disposed on the bottom portion of the insole at one or more judiciously selected locations to provide different heights and/or different physical properties. An orthopedic shoe is also provided having an upper; a sole attached to the upper, and the removable insole within the shoe. An orthopedic insole is provided with an insole having a bottom portion for facing a sole of a shoe; a first orthopedic pad disposed on the bottom portion of the insole at a location corresponding to at least one selected from the group consisting of a medial longitudinal arch, a lateral longitudinal arch, and a transverse metatarsal arch of a foot.

An orthopedic insole and a method of manufacturing a convex cushion structure for walking unsteadiness, the convex cushion structure being provided on an upper surface of an insole body. The method includes steps of data collection: measuring plantar static pressure data and plantar dynamic pressure data; data analysis: analyzing the plantar static pressure data and the plantar dynamic pressure data; preparing an insole body; performing insole modeling based on the plantar static pressure data; and importing the plantar dynamic pressure data to manufacture the insole body; partitioning the insole body; preparing the convex cushion structure: determining a shape of the convex cushion structure by using a test result of the dynamic pressure distributions; determining a specific location of the convex cushion structure by using a test result of the gait lines and the gait cycle; and printing the convex cushion structure on the upper surface of the insole body.

Disclosed herein are various methods and devices for modifying the comfort and performance characteristics of a shoe. In various embodiments, the devices are soles, insole or outsoles, of a shoe comprising one or more shocks. The shocks may be defined by shock cavities positioned within one or more surfaces of a sole. In some embodiments the shock cavity may be configured to receive one or more shock cavity inserts.

A removable wedge for ski boots, which is adapted to be fixed in a movable manner inside a ski boot, resting on the bottom of the foot-casing of the ski boot, and is characterised in that it comprises: a platelike rigid body made of plastic material; and a piece of fabric which is embedded in the platelike rigid body in order to emerge over the lower face of the platelike rigid body, and additionally has an adhesive layer on the part that emerges outside of said platelike rigid body; the platelike rigid body being injection-moulded directly over said piece of fabric.

The present invention is footwear having a convex shaped outsole with opposing wedge shaped configurations in the bottom of the front sole section and the back sole section which provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The present invention is also footwear convex shaped in the longitudinal direction with a split sole having opposing wedge shaped configurations in the bottom of the front sole section and the back sole section that provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The invention further includes footwear having at least one pair of wedges on the outsole which provide footwear having improved arch support. The invention is also footwear with a flexible, elastic, member between the front sole section and the back sole section of the sole.

Embodiments are directed to an insole for footwear. The insole preferably includes a bottom surface, a peripheral sidewall, and a relief. The bottom surface has a perimeter, and the peripheral sidewall preferably extends upward from the perimeter of the bottom surface. The relief is preferably disposed in the peripheral sidewall.

The present invention provides an improved orthotic device adapted to be inserted into a high-heeled or raised-heel shoe and to receive a human foot thereon. The orthotic device may be operable to adhere to the sole of the shoe and may comprise a proximal contoured slope operable to prevent migration and increase acceptance of body weight at the heel of the wearer's foot and may comprise a distal contoured slope operable to support the arch of the wearer's foot, preventing the foot from sliding forward and focusing excessive painful pressure at the user's toes. The orthotic device may also have dual layers of adhesive material separated by a peel-away backing, and an inferior surface concavity with a channel allowing solvent to be used to dissolve the adhesive if the orthotic device needs to be repositioned or changed to a new shoe.
