Benefits of technology

[0066]The design of the preferred embodiment incorporates a rearfoot, midfoot and forefoot valgus design that assists the foot to withstand the supinatory forces caused by the constant activation of the windlass mechanism and therefore provides

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

Embodiment Construction

[0074]A valgus wedged orthoses or orthotic device 10 is disclosed herein for use primarily with heeled shoes of more than 3 cm. However the orthotic device 10 can be used in other shoe types including sports, flat, sandal and dress shoes. The orthotic device 10 concentrates the support under the lateral rearfoot, lateral midfoot and lateral forefoot, minimizing the degree of supination of the foot. The biomechanical changes that occur by minimizing the degree of supination of the foot in a heeled shoe include stabilisation of the lateral ankle, unloading of the peroneal and lateral gastrocnemius musculature and reduced out-of-phase activation of the flexor and extensor musculature.

[0075]Existing orthotics for heeled shoes feature support concentrated in the medial arch and some comprise of a varus wedge of the rearfoot and / or forefoot, potentially exacerbating the negative biomechanical changes associated with a heeled shoe. The orthotic device 10 disclosed herein provides the oppos...

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...
