AI Technical Summary

Benefits of technology

The present invention is an orthotic insole with a contoured surface that matches the shape of a foot. It includes an inflatable bladder that adjusts to different support needs by the foot. This allows for additional support without changing the shape of the insole. The bladder can be inflated or deflated to provide the required level of support in the arch region. The technical effect is to provide a comfortable and customizable orthotic insole that provides proper support and comfort for the foot.

Problems solved by technology

Whilst the orthotic provides a greater degree of support than a simple resilient insole, it is relatively expensive to make and, once made, is of fixed configuration.
As such it is not able to accommodate different situations that might arise, such as use during a high impact sport activity or use in casual footwear where less underlying structure is available to support the orthotic.
None of the prior art addresses the need for an insole that can accommodate varying needs of the user.

Embodiment Construction

[0020]Referring firstly to FIG. 1, an insole 10 has a body 12 with a toe region 14, a heel region 16 and an arch region 18. An upper support surface 20 of the body is contoured to conform to the underside of the user's foot and a bladder 22 is located within the body 12 in the arch region.

[0021]As can be seen from FIG. 2, the body 12 has a tray 24 formed from a rigid plastics material with upturned edges 26. The tray 24 extends along the body 12 from the heel region 16 to forward of the arch region 18 and terminating before the toe region 14. The tray 24 has an aperture 28 to receive a resilient heel pad 30 that is attached to the underside of a molded core 32. The heel pad 30 acts as a shock absorber and may be made from a high tensile strength polyurethane sheet material. A similar pad 34 is fixed to the core under the toe region 14 to provide a shock absorber in the toe region.

[0022]The core 32 is molded from a flexible plastics, such as EVA, which is relatively inelastic to resi...

Abstract

An orthotic insole with a contoured support surface to conform to the underside of a foot. An arch support is provided by an inflatable bladder located within the insole and having a pump in the heel region of the insole to allow adjustment of the bladder. A valve is provided at the side of the bladder to release air from the bladder.

Description

RELATED APPLICATIONS[0001]This application claims priority from U.S. provisional application 62 / 469,619, filed Mar. 10, 2017, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to an insole suitable for use with footwear such as shoes, boots or the like.DESCRIPTION OF THE PRIOR ART[0003]It is common practice to provide an insole for footwear to increase the comfort or utility of the footwear. Typically such insoles are resilient to provide a degree of cushioning for the user in an attempt to reduce fatigue in the foot of the user. The resilient insoles may be planar and provide a layer of cushioning overlying the interior of the sole of the footwear.[0004]It is also known to use an insole to provide support to a user's foot. These insoles, commonly referred to as orthotics, have a contoured upper surface that is complimentary to the underside of the user's foot and so provides support for the foot within the footwear....
