Abstract

A flexible pillar sole member is provided for attachment to the front portion of a shoe thereby causing the wearer to stand, walk and run without touching his heels to the ground. The resultant shoe provides for dynamic exercise.

Claims

1. An exercise shoe having a shoe vamp and a pillar sole member, said pillar sole member having a top, an intermediate portion and a bottom sole, said top being connected to said vamp in the area extending from the ball of the foot area forwardly to the toe area, said bottom sole extending laterally beyond the outer side of the vamp, said intermediate portion having at least one concave portion to facilitate distortion, said pillar sole member being of a height and compliance which makes difficult the touching of the heel area of the vamp to the supporting surface engaged by the bottom sole.

2. An exercise shoe having an elevating extension secured to the bottom of the sole thereof at the area adjacent the ball of the human foot, and a ground contacting sole carried by the end of the elevating extension remote from the shoe sole, said ground contacting sole extending laterally beyond the shoe sole at the outside of the shoe.

3. The shoe set forth in claim 6 wherein said ground contacting sole is flexible.

4. The shoe set out in claim 2 wherein said ground contacting sole extends laterally beyond the shoe sole at the inside of the shoe.

5. The shoe set out in claim 2 wherein said ground contacting sole has dimensions and distortability coordinated with the user'"'"''"'"'s size and weight.

6. An exercise shoe having a shoe vamp and a pillar sole member;

said pillar sole member having a top, an intermediate portion and a bottom sole, said top being connected to said vamp in the area extending from the ball of the foot to the toe area, said intermediate portion sloping rearwardly and downwardly from the front connection at said toe area to facilitate distortion, said bottom sole only underlying the vamp from substantially the toe area to the area of the ball of the foot, said pillar sole member being of a height and compliance which makes difficult the touching of the heel area of the shoe to the supporting surface engaged by the bottom sole.

7. The shoe set forth in claim 6 wherein said bottom sole has dimensions and distortability coordinated with the user'"'"''"'"'s size and weight.

8. The shoe set forth in claim 7 wherein the height of the intermediate portion is in the neighborhood of 2 to 3 inches.

9. The shoe set forth in claim 6 wherein said bottom sole extends laterally beyond the vamp at the outer side of the shoe.

10. The shoe set forth in claim 9 wherein said bottom sole extends laterally beyond the vamp at the inner side of the shoe.
