Abstract

Abstract Disclosed herein is a new and improved running shoe in which the structure and anatomy of the shoe, including the upper and the thermoplastic rubber unit bottom to which it is secured is balanced and synchronized with the complex action of the wearer's foot in order to tend to optimize the functioning of the multitudinous bones and muscles of the foot and leg during running movements, in general, and during the mid-stance period of the running gait in particular. The unit bottom of the new running shoe has a specially configured and contoured plantar surface having a narrow throat portion with specially shaped integral medial and lateral pad portions disposed therein intermediately of the anterior and posterior portions thereof. The dorsal surface of the new unit sole is generally contoured to conform faithfully to the anatomy of the plantar portion of the wearer's foot when the foot is in its neutral position. In general, the overall construction of the unit bottom, including its specific geometry and its honeycombed internal support, is arranged to accommodate and to promote proper flexion and extension of the wearer's foot during pronated and supinated movements of the foot and leg during running and striding, and in particular during the "stance" portion of the runner's gait, i.e. the portion of the gait in which the foot is in contact with the ground. The upper of the new running shoe is of generally ultra-lightweight porous material and reinforced with leather to provide a roomy boxed toe configuration in the distal part and a cushioned, high heel counter portion in the proximal part of the shoe. In addition, an independent heel cushion is interposed between a lightweight insole and the distal dorsal surfaces of the unit bottom. Moreover, cooling channels are formed on the dorsal anterior and posterior surfaces of the unit bottom, which channels communicate with ports exposed to the atmosphere at the leading and trailing edges of the unit bottom to allow for air cooling.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 161 words
In a running shoe comprising a unit bottom of elastomeric resilient material, (and) an upper cemented to said bottom, and a full length resilient insole superimposed upon said bottom, the improvement characterized in that (a) the lowermost, ground-contacting, treading portion of said bottom has a generally oval plantar forepart and a generally oval plantar heel part interconnected by a narrow throat portion; (b) said throat portion comprising a lateral pad and a medial pad; (c) each of said pads being offset from the longitudinal center line of said bottom; (d) said lateral pad being disposed anteriorly within said throat portion; (e) said medial pad being disposed posteriorly within said throat portion; (f) the dorsal portions of said bottom of said throat portions forming first and second pairs of valleys bounding said lateral and medial pads respectively and separating said oval heel part from said oval forepart, and (g) said first and second pairs of valleys being longitudinally offset from each other.
Claim 2
Dependent Claim 161 words
In a running shoe comprising a unit bottom of elastomeric resilient material, (and) an upper cemented to said bottom, and a full length resilient insole superimposed upon said bottom, the improvement characterized in that (a) the lowermost, ground-contacting, treading portion of said bottom has a generally oval plantar forepart and a generally oval plantar heel part interconnected by a narrow throat portion; (b) said throat portion comprising a lateral pad and a medial pad; (c) each of said pads being offset from the longitudinal center line of said bottom; (d) said lateral pad being disposed anteriorly within said throat portion; (e) said medial pad being disposed posteriorly within said throat portion; (f) the dorsal portions of said bottom of said throat portions forming first and second pairs of valleys bounding said lateral and medial pads respectively and separating said oval heel part from said oval forepart, and (g) said first and second pairs of valleys being longitudinally offset from each other.
Claim 3
Dependent Claim 40 words
The running shoe of claim 1, further characterized in that (a) said forepart is elevated at an angle with respect to the generally horizontal plane of said heel part and said throat portion, whereby said forepart has substantial toe spring.
Claim 4
Dependent Claim 19 words
The running shoe of claim 1, further characterized in that (a) said heel part has a slight transverse concavity.
Claim 5
Dependent Claim 35 words
The running shoe of claim 1, further characterized in that (a) the uppermost foot-supporting portions of said unit bottom are generally contoured to conform to the anatomy of the plantar portions of the human foot.
Claim 6
Dependent Claim 20 words
The running shoe of claim 1, further characterized in that (a) the posterior-most portions of said heel part are beveled.
Claim 7
Dependent Claim 20 words
The running shoe of claim 1, further characterized in that (a) said unit bottom is fabricated from a styrene-butadiene-block copolymer.
Claim 8
Dependent Claim 70 words
The running shoe of claim 1, in which (a) said first and second pairs of valleys each include a deep valley and a shallow valley; (b) said lateral pad is separated from said forepart by a shallow valley and from said heel part by a deep valley; and (c) said medial pad is separated from said forepart by a deep valley and from said heel part by a shallow valley.
Claim 9
Dependent Claim 147 words
A running shoe bottom comprising (a) a one-piece molded sole of resilient elastomeric material having a bottom round-indicating tread surface and an upper foot supporting surface; (b) said bottom has a generally oval plantar forepart and a generally oval plantar heel part interconnected by a narrow throat portion; (c) said throat portion comprising a lateral pad and a medial pad; (d) each of said pads being offset from the longitudinal center line of said bottom; (e) said lateral pad being disposed anteriorly within said throat portion; (f) said medial pad being disposed posteriorly within said throat portion; (g) the lowermost portions of said bottom at said throat portions forming first and second pairs of valleys bounding said lateral and medial pads respectively and separating said oval heel part from said oval forepart, and (h) said first and second pairs of valleys being longitudinally offset from each other.
Claim 10
Dependent Claim 147 words
A running shoe bottom comprising (a) a one-piece molded sole of resilient elastomeric material having a bottom round-indicating tread surface and an upper foot supporting surface; (b) said bottom has a generally oval plantar forepart and a generally oval plantar heel part interconnected by a narrow throat portion; (c) said throat portion comprising a lateral pad and a medial pad; (d) each of said pads being offset from the longitudinal center line of said bottom; (e) said lateral pad being disposed anteriorly within said throat portion; (f) said medial pad being disposed posteriorly within said throat portion; (g) the lowermost portions of said bottom at said throat portions forming first and second pairs of valleys bounding said lateral and medial pads respectively and separating said oval heel part from said oval forepart, and (h) said first and second pairs of valleys being longitudinally offset from each other.
