Flexible orthotic device

Abstract

An orthotic device which provides functional support for the foot. It comprises a substantially rigid moulded sheet of resiliently deformable plastics material which provides continuous contact with the arch of the foot whether the foot is flat or pointed. The plastics material is preferably embedded between a shock absorbent layer and a covering layer.

Description

[0001] This invention relates to orthotic devices and is particularly concerned with resiliently flexible orthotic devices which are designed to provide functional support for the foot without inhibiting the functional motion of the foot.[0002] The invention will primarily be described in relation to inserts for footwear, particularly performance footwear such as dancing, ballet and athletic shoes, however it also extends to orthotic devices which are fitted directly to the foot or indirectly with the use of some form of containment such as hosiery, bandages, strapping or layered materials. These broader aspects of the invention should therefore be borne in mind and the following description of preferred embodiments should not be deemed to be any way limiting on the scope of the invention.[0003] When it comes to providing functional assistance and comfort to the foot, dancers have always been at a disadvantage. This is due mainly to the restrictive accommodation of dancing footwear ...

AI Technical Summary

Benefits of technology

[0008] It is therefore an object of the invention to provide an orthotic device which will enhance the arch profile and performance of the foot, particularly in restrictive performance footwear.

[0009] It is a further object of the invention to provide protection to the foot from abnormal impact forces.

Problems solved by technology

When it comes to providing functional assistance and comfort to the foot, dancers have always been at a disadvantage.

This is due mainly to the restrictive accommodation of dancing footwear as exemplified by ballet slippers.

Any insole with support or support padding limits the range of foot function (flat foot position to en pointe) and also causes the slipper to bulge out, especially at the inner side of the foot.

These types of insoles are not functionally or aesthetically acceptable.

Dancers and other athletes who perform high impact and repetitive activities with their feet often develop soft tissue and bone pathology in the foot and leg.

This situation is compounded when supportive and cushioned footwear cannot be worn during these activities.

Dancers who wear ballet slippers are particularly at risk and suffer a number of painful conditions ranging from aches, cramps and tendonitis to stress fractures or complete fracture of the bones in the feet.

Gymnasts, boxers and sprinters have similar problems.

When the muscles which control these movements are weak or used inappropriately the foot cannot sustain good function.

Poor foot structure also results in poor foot function.
