AI Technical Summary

Benefits of technology

The present invention is a shoe that uses different components to provide cushioning and support for the user's foot depending on their needs. It can offer enough cushioning for normal use or for more strenuous activities like carrying a heavy backpack or walking on difficult terrain. The shoe also provides control by offering a rigid structure that can limit the bending and twisting of the foot, but can also adjust to provide more forgiving limited motion of the user. This allows for better control and comfort during use.

Problems solved by technology

The human foot is a very complex biological mechanism.
Like most custom made items, custom insoles tend to be expensive because of the low volume and extensive time needed to make and fit them properly.
As such, it is not practical to make such custom made insoles for the general public.
These patents, however, do not address the need for individualized customization of the insole based on the components of the insole that are positioned or integrated into the insole.
Insoles in the prior are placed inside shoes, but the various designs in the prior art do not offer individualized customization along with sufficient cushioning and support attributes.

example 1

[0413]Scenario: Patient reports burning pain beneath the left big toe joint. Intermittent episodes of pain with sports for many years. Worse since starting step classes three times a week. Had to pull out of the last class due to severe soreness.

[0414]Examination: Pain with direct pressure beneath the inflamed first metatarsophalangeal joint (MTPJ), especially over the tibial sesamoid. Plantarflexed first metatarsals bilaterally, plus a forefoot valgus on the left foot.

[0415]Diagnosis: Tibial Sesamoiditis.

[0416]Treatment: A forefoot wedge may be applied to the left insole to further redirect ground reaction forces (GRF) away from the painful first metatarsal head. Heel cushions may be applied to maintain the magnitude of GRF forces beneath the central heel.

[0417]Alternatively, the insoles may be delivered to the user with the heel cushions and first metatarsal head pads pre-attached before application of additional components by the user. For this example, adjustments may need to be...

example 2

[0424]Scenario: Patient reports painful lump on the ball of the left foot. Calluses have been on the soles of both feet for many years, but the left foot has become increasingly more red, swollen, and painful over the last three months.

[0425]Examination: Area of thick callus with edema and erythema beneath the left second MTPJ. Bilateral excessive foot pronation with calcaneal eversion in static stance and gait. 0° ankle joint dorsiflexion bilaterally. Metatarsus Primus Elevatus on the left foot.

[0426]Diagnosis: Plantar Metatarsal Bursitis.

[0427]Treatment: The metatarsal dome and cushioned forefoot extension will reduce excessive GRF beneath the 2nd MTPJ. Rigid arch supports and rearfoot wedges may be applied to reduce the excessive pronation moments. Heel lifts may be used for the ankle equinus if the shoe style permits. First metatarsal head pads and heel cushions may be applied to maintain the magnitude of GRF forces beneath the first metatarsal heads and central heel.

example 3

[0447]Scenario: Patient reports painful lumps on the outside of the balls of the feet.

[0448]Examination: Bilateral Intractable Plantar Keratosis (IPK) with swelling and erythema beneath the 5th metatarsal head. Inverted heel positions in static stance and gait and bilateral forefoot valgus.

[0449]Diagnosis: Plantar metatarsal bursitis with overlying IPK.

[0450]Treatment: Forefoot wedges should be applied to both insoles to off-load the 5th metatarsal heads and to reduce the degree of heel inversion. First metatarsal head pads and heel cushions may be applied to maintain the magnitude of GRF forces beneath the first metatarsal heads and central heel. If symptoms persist, adjust the first metatarsal head pads to enhance the effect of the metatarsal dome and forefoot wedges.

[0451]Alternatively, the insoles may be delivered to the user with the heel cushions and first metatarsal head pads pre-attached before application of additional components by the user.

[0452]The forefoot wedge area be...

Abstract

This invention provides for individualized adjustment to a user's specific needs through the use of multiple variable size, thickness and rigidity components that can be placed or integrated into an insole. The current invention is an insole that incorporates, but is not limited to: (1) a base layer with various depressions, (2) a metatarsal dome, (3) a first metatarsal head pad, (2) a forefoot wedge to create a pronation moment around the midfoot joint, (3) a heel cushion, (4) a heel lift to raise the heel area of the foot, (5) a rearfoot wedge to increase the supination moments around the subtalar joint, and (6) an arch support of a specific stiffness or with varying stiffness.

Description

RELATED APPLICATION DATA[0001]This application is related to Provisional Patent Application Ser. No. 61 / 929,944 filed on Jan. 21, 2014, and priority is claimed for this earlier filing under 35 U.S.C. §119(e). The Provisional Patent Application is also incorporated by reference into this patent application.TECHNICAL FIELD[0002]The present invention relates to a shoe insole with customizable cushioning and support to the foot of a wearer.BACKGROUND OF THE INVENTION[0003]The human foot is a very complex biological mechanism. The many bones, muscles, ligaments, and tendons of the foot, function to absorb and dissipate the forces of impact. The load on the foot at heel strike is typically about one and a half times a person's body weight when a person walks. When running or carrying extra weight, such as a backpack, loads on the foot can exceed three times the body weight.[0004]The many bones, muscles, ligaments, and tendons of the foot function to absorb and dissipate the forces of impa...
