Orthotic device for shoes

Abstract

An orthotic device (10) for use with heeled, dress, flat or sport shoes, the device (10) comprising a body (25), a medial arch support (40) defined by a projection extending upwardly away from the body (25); and a valgus wedge (20) defined by a projection located at a lateral rear foot portion and / or a lateral forefoot portion of the body (25), the valgus wedge (20) being adapted to evert the foot and concentrate the support of the device (10) laterally.

Description

TECHNICAL FIELD[0001]The present disclosure relates to an orthotic device for shoes. In particular, the present invention relates to an orthotic device for dress shoes. However, it will be appreciated by those skilled in the art that the present invention may be used in other applications and in particular with other shoe types.BACKGROUND OF THE INVENTION[0002]Foot orthotic devices (also known as orthoses) are commonly prescribed by health professionals to alter foot kinetics, improve function, provide cushioning, reduce pain, prevent injury and redistribute forces acting upon the lower limb musculoskeletal system.[0003]Foot orthotic devices may be made to an individual's customized prescription or manufactured for the mass population and are usually designed specifically for a certain type of footwear including running shoes, work shoes and high heels.[0004]A customised orthotic prescription is made from an impression of the individual's foot and manufactured to a personalised pres...

AI Technical Summary

Benefits of technology

This patent describes an orthotic device that provides cushitioning, foot support, and ankle stability using lateral foot support, medial arch support, and shock-absorbing materials. The device also includes a unique high heel insole structure that reduces biomechanical complications associated with heeled shoes. The invention also incorporates shock-absorbing material and recruits secondary ankle stabilizers to prevent over-supination. The design also assists the foot to withstand the supinatory forces caused by the constant activation of windlass mechanisms, reducing muscle fatigue and pain.

Problems solved by technology

Although the windlass mechanism is commonly appreciated by those skilled in the field, the link between heeled shoes causing the over-activation of the windlass mechanism leading to ankle instability and subsequent pain is unidentified by those in the field and the literature.

Orthoses that concentrate support on the medial arch and / or medial foot including a varus wedge will amplify over-supination, contributing further instability and associated pathologies when used in heeled shoes.
