Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
186 words
A foot-massaging sandal having forward, central and rear portions and comprising: an outer sole with a thicker resilient insole overlying said outer sole and secured thereto; said insole having an upper face on the forward portion of which there is an elevation extending transversely from one side of the face toward the opposite side whereby to underlie and be gripped by the outer four toes of a foot for exercising the same; a plurality of spaced ridges integrally formed with, and upstanding from, the upper face of said insole to exert a massaging action on the foot during use of the sandal; the central portion of said face having said ridges extending substantially the width of said central portion; the rear portion of said face having said ridges extending from one side and short of the opposite side thereof; said ridges being at least as wide at juncture with said upper face as their height and flexing only vertically with the flexing of said insole due to the variance in foot pressure while walking; and means for attaching the sandal to the foot of a user.
Claim 2
Dependent Claim
186 words
A foot-massaging sandal having forward, central and rear portions and comprising: an outer sole with a thicker resilient insole overlying said outer sole and secured thereto; said insole having an upper face on the forward portion of which there is an elevation extending transversely from one side of the face toward the opposite side whereby to underlie and be gripped by the outer four toes of a foot for exercising the same; a plurality of spaced ridges integrally formed with, and upstanding from, the upper face of said insole to exert a massaging action on the foot during use of the sandal; the central portion of said face having said ridges extending substantially the width of said central portion; the rear portion of said face having said ridges extending from one side and short of the opposite side thereof; said ridges being at least as wide at juncture with said upper face as their height and flexing only vertically with the flexing of said insole due to the variance in foot pressure while walking; and means for attaching the sandal to the foot of a user.

A foot-massaging sandal according to claim 1, wherein said front portion of said face has ridges which are shorter than the ridges on the rear portion of the face.
Claim 4
Dependent Claim
31 words
A foot-massaging sandal according to claim 1, wherein said front portion of said face has ridges which are spaced farther apart than the ridges on the rear portion of the face.
Claim 5
Dependent Claim
40 words
A sandal according to claim 1, wherein said transverse elevation drops off adjacent to said opposite sIde to leave an area adapted to receive the great toe of the foot and which area has short ones of said ridges thereon.
Claim 6
Dependent Claim
51 words
A sandal according to claim 1, wherein said ridges on the central portion are adapted to underlie the longitudinal arch of the foot and a group of ridges is provided forwardly adjacent to said central portion ridges and adapted to underlie the rear portion of the metatarsal arch of the foot.
Claim 7
Dependent Claim
25 words
A sandal according to claim 5, wherein said central portion ridges and said group of ridges are higher than the ridges elsewhere on said face.
Claim 8
Dependent Claim

A sandal according to claim 1, wherein said insole including said ridges is molded integrally from polyurethane foam having a relatively soft foam interior covered by a dense tough skin providing said upper face and including said elevation and said ridges.
Claim 9
Dependent Claim
31 words
A sandal according to claim 1, wherein one of said ridges defines the upper bounding edge of said face and other of said ridges have ends merging with said bounding edge.
Claim 10
Dependent Claim
42 words
A sandal according to claim 1, wherein said forward portion of the upper face has areas which are smooth and devoid of ridges rearwardly adjacent to said elevation and adapted to receive the first and fifth metatarsal heads of the foot thereon.
Claim 11
Dependent Claim
69 words
A sandal according to claim 1, wherein said ridges on the rear portion of said face are adapted to lie under the heel of the foot and are spaced closer in the central area of the rear portion to lie under the os calcis and spaced farther apart at the sides of the rear portion where adapted to lie under the fleshy tissue adjacent the sides of the heel.
