Abstract
Abstract An athletic shoe particularly adapted for use in sports where sudden turns, starts, stops and lateral movements are involved, in which the sole 14 includes a lengthwise concavity 46 for gripping action; the medial aspect 54 of the sole is linear and rouned off from about the first metatarsal extension up to and including the heel; the sole includes a two-tiered construction from the first metatarsal phalangal joint to distal at 58 to the fifth metatarsal head at 60 so a lowered area at 64 casts the user's weight forwardly to assist in sudden starts; the lateral edge 52 of the sole comprises a projecting wing 90 from the generally vertical side of the shoe; the heel is flared on the lateral edge and a projecting wing 72 is provided from behind the fifth metatarsal to just below the malleolus and around the heel to meet the aforementioned medial wing; and the posterior aspect of the sole is beveled; the shoe having a wrapped around construction on the exterior affording support for the user's foot.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
121 words
In an athletic shoe comprising an upper portion integral with a sole portion, said upper portion including medial and lateral side portions integral with corresponding medial and lateral side portions of said sole portion, said upper portion including a heel portion and toe portion integral with corresponding portions of said sole portion, and said upper portion including means for securing a user's foot in said shoe, the improvement comprising: the medial aspect of the sole portion being linear and radiused at least from the ball of the foot toward the heel and beneath and the extent of the plantar arch for permitting the entire medial edge to readily rotate and support the user's foot during maximum pronation over said medial edge.
Claim 2
Dependent Claim
121 words
In an athletic shoe comprising an upper portion integral with a sole portion, said upper portion including medial and lateral side portions integral with corresponding medial and lateral side portions of said sole portion, said upper portion including a heel portion and toe portion integral with corresponding portions of said sole portion, and said upper portion including means for securing a user's foot in said shoe, the improvement comprising: the medial aspect of the sole portion being linear and radiused at least from the ball of the foot toward the heel and beneath and the extent of the plantar arch for permitting the entire medial edge to readily rotate and support the user's foot during maximum pronation over said medial edge.
Claim 3
Dependent Claim
55 words
The structure as claimed in claim 1 in which the radiused medial aspect extends from just above the great toe joint to the scaphold and continues through to the heel whereby the shoe and foot therein are in full contact with a support surface and maximum support is provided for the plantar arch during pronation.
Claim 4
Dependent Claim
99 words
The structure as claimed in claim 1 in which the lateral edge of the sole portion extends substantially beyond the lateral side portion of the upper portion of the shoe, the heel portion of the sole portion including a lateral projection from behind and fifth metatarsal to just below the lateral malleous and around the heel to meet the extending portion of the lateral edge of the sole and providing essentially an outrigger for preventing foot-inversion during running laterally or backward and increasing in a tactile sense the lateral aspect of the foot for aiding to prevent sprained ankles.
Claim 5
Dependent Claim
31 words
The structure as claimed in claim 1 in which the posterior aspect of the sole in the heel area is beveled for affording quick rollover and increased dorsiflexion of the foot.
Claim 6
Dependent Claim
77 words
The structure as claimed in claim 1 in which said shoe includes a wedge-shaped cushioning portion tapering forwardly from the heel portion and overlying said sole portion, said wedge portion extending from the heel to just behind the metatarsal head within the shoe for functionally shortening the calf muscle of a user of the shoe to reduce Achilles-tendenitis, causing extension of the sole of the user's foot at the first metatarsal phalangeal joint for immediate ground contact.
Claim 7
Dependent Claim
44 words
The structure as claimed in claim 1 in which said sole portion includes in its lower surface a longitudinal concavity inwardly of the respective medial and lateral edges of the sole and extending from the heel portion to adjacent the ball of the foot.
Claim 8
Dependent Claim
37 words
The structure as claimed in claim 6 in which said concavity includes a plurality of transverse ribs therewithin and increasing the longitudinal flexibility of the sole at said concavity for promoting suction and gripping of the sole.
Claim 9
Dependent Claim
58 words
The structure as claimed in claim 1 in which said sole portion includes as integral projection extending upwardly to an intermediate portion of both the medial and lateral side portions of the shoe and generally at opposite sides of the respective plantar and metatarsal arch areas, said integral projection extending around the heel portion of the shoe upper.
Claim 10
Dependent Claim
53 words
The structure as claimed in claim 1 in which the sole includes an essentially two-tiered construction feathered from about the first metatarsal phalangeal to the fifth metatarsal head along a transverse margin and defining forwardly thereof a lowered area for concentrating a user's weight forwardly and essentially on the ball of the foot.
Claim 11
Dependent Claim
131 words
In an athletic shoe comprising an upper portion integral with a sole portion, said upper portion including lateral and medial side portions integral with lateral and medial sole portions said upper portion including a heel portion and a toe portion integral with corresponding portions of said sole portion, said upper portion including means for securing a user's foot in said shoe, the improvement comprising: the medial aspect of the sole portion being in a single plane, linear from about the ball of the foot to substantially adjacent the heel area for providing substantial full linear contact along the linear sole edge in a single plane with a support surface and supporting a user's foot along the long plantar arch during placement of the foot and imposition of the user's weight thereon.
Claim 12
Dependent Claim
131 words
In an athletic shoe comprising an upper portion integral with a sole portion, said upper portion including lateral and medial side portions integral with lateral and medial sole portions said upper portion including a heel portion and a toe portion integral with corresponding portions of said sole portion, said upper portion including means for securing a user's foot in said shoe, the improvement comprising: the medial aspect of the sole portion being in a single plane, linear from about the ball of the foot to substantially adjacent the heel area for providing substantial full linear contact along the linear sole edge in a single plane with a support surface and supporting a user's foot along the long plantar arch during placement of the foot and imposition of the user's weight thereon.
Claim 13
Dependent Claim
45 words
The structure as claimed in claimed in claim 10 in which said sole portion includes an integral portion extending upwardly to an intermediate portion of the exterior of said shoe upper portion and providing exterior arch support at least at the long plantar arch area.
Claim 14
Dependent Claim
35 words
The structure as claimed in claim 10 in which said upwardly extending portion has an upper, arcuate margin conforming substantially to the long plantar arch area above the sole and exteriorally of the shoe upper.
Claim 15
