Abstract
Abstract A foot or fifth toe support for any shoe but primarily for running and jogging shoes, consisting of a flat, flexible and resilient member located below the fifth proximal phalanx from the metatarsal-phalanx joint to the proximal phalanx neck. This support lies independently on the upper surface of a conventional shoe sole or it may be an extension of a semi-rigid orthotic device contoured and dimensioned to cradle the sole and heel to a line across the foot near the distal ends of the metatarsal bones.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
77 words
A foot support structure comprising: base means conforming generally to the contour of the sole of a human foot; and means attached to said base means extending substantially only under the fifth phalanx of said foot for compensating for lateral imbalance of said foot by establishing an effective amount of inward rotation of said foot for efficient forward thrust and preventing outward rotation of said foot during running for maximizing effective foot and body motion for running.
Claim 2
Dependent Claim
77 words
A foot support structure comprising: base means conforming generally to the contour of the sole of a human foot; and means attached to said base means extending substantially only under the fifth phalanx of said foot for compensating for lateral imbalance of said foot by establishing an effective amount of inward rotation of said foot for efficient forward thrust and preventing outward rotation of said foot during running for maximizing effective foot and body motion for running.
Claim 3
Dependent Claim
26 words
The support structure of claim 1 wherein said extending means extends from said base means to about the midportion of the fifth phalanx of said foot.
Claim 4
Dependent Claim
13 words
The support structure of claim 1 wherein said base means is substantially stiff.
Claim 5
Dependent Claim
32 words
The support structure of claim 1 wherein said extending means is resilient for maximizing the effective forward thrust provided by the bending and unbending of the toes of said foot during running.
Claim 6
Dependent Claim
40 words
The support structure of claim 1 wherein said extending means has a thickness sufficient to compensate for lateral imbalance of said foot as measured at a line across said foot at the midportions of the phalanx bones of said foot.
Claim 7
Dependent Claim
20 words
The support structure of claim 1 wherein said support structure is incorporated in a support for insertion into a shoe.
