Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
221 words
A running sole for a shoe, said sole comprising a sole body of softly resilient material in the heel region, said body having a longitudinal axis, an upper surface of said body located below the heel of the wearer and a lower surface of the body, a rear edge and two side edges of the body joined by said rear edge, a first generally longitudinally extending recess formed in the body, below the upper surface and above the lower surface and opening at one edge thereof, at least one generally transversely extending second recess in the body below the upper surface and above the lower surface and opening into at least one of said two side edges, said at least one second recess intersecting said first recess, a first springably compressible and flexible supporting body exchangeably insertable into said first recess and having a cross-section largely filling the cross-section of said first recess, a second springably compressible and flexible supporting body exchangeably insertable into said at least one second recess, and having a cross-section largely filling the cross-section of said second recess, at least one opening in one of said first and second supporting bodies and a portion of the other of said first and second supporting bodies being engageable in said at least one opening in said one supporting body.
Claim 2
