Abstract

A footwear device is provided having a deformable heel contact member. The heel contact member extends above a top portion of the footwear'"'"'s sole and deforms into a cavity formed in the sole when the user'"'"'s heel applies a force against the heel contact member. The heel contact member is resilient and returns to its original shape when the force against the heel contact member is eliminated. The heel contact member is particularly well suited to reduce heel slap of open heeled footwear.

Claims

1. A footwear device, said device comprising:

a sole member having a top portion and a bottom portion, wherein the top portion of said sole member is divisible into a toe receiving segment, a mid-segment and a heel receiving segment;

a foot retaining member coupled to said sole member;

said heel receiving segment of said sole member includes a cavity formed in and extending into said sole member at said heel receiving segment, wherein said cavity extends into said sole member from the top portion of the heel receiving segment of said sole member; and

a pliable lever coupled to said sole member at said heel receiving segment of said sole member, said pliable lever having a first free end and a second fixed end, wherein said first free end pivots downward into said cavity formed in said sole member and further wherein the second fixed end is coupled to the sole member within the cavity formed in the sole member.

2. The device as recited in claim 1, wherein said foot retaining member is comprised of a strap having opposing ends of said strap fixed to said sole member at the mid segment of said sole member.

3. The device as recited in claim 1, wherein the first free end of said pliable lever has a heel contact portion that extends above the top portion of said sole member when said pliable lever is in a relaxed position.

4. The device as recited in claim 3, wherein said pliable lever deforms when a force is directed towards said heel contact portion of the pliable lever.

5. The device as recited in claim 4, wherein when the pliable lever deforms at least a portion of the pliable lever recedes into the cavity formed in the sole member.

6. The device as recited in claim 1, wherein said pliable lever deforms under a heel weight of a user.

7. A footwear device, said device comprising:

a sole member having a top portion and a bottom portion, wherein said top portion of said sole member includes a toe receiving portion, a mid-portion and a heel receiving portion;

a foot retaining member coupled to said sole member;

said heel receiving portion including a cavity formed in and extending into said sole member from the top portion of the heel receiving portion of said sole member; and

a lever arm coupled to said sole member at said heel receiving portion of said sole member, said lever arm having a first relaxed position wherein an upper free end portion of said lever arm extends above the top portion of the sole member when in the relaxed position, said lever arm further having a second position wherein said upper free end portion of said lever arm pivots into said cavity formed in said heel receiving portion of said sole member when a force is applied against said lever arm.

8. The device as recited in claim 7 wherein said lever arm deforms when a heel presses against the upper free end portion of the lever arm.

9. The device as recited in claim 8, wherein when said lever arm deforms at least a portion of the upper free end of the lever arm recedes into the cavity formed in the sole member.

10. The device as recited in claim 7, wherein said foot retaining member is comprised of a strap having opposing ends of said strap fixed to said sole member at the mid portion of said sole member.

11. The device as recited in claim 7, wherein a portion of said lever arm has a flattened upper and lower surface.

12. The device as recited in claim 7 wherein said lever arm deforms under a heel weight of a user.

13. A footwear device, comprising:

a sole member having a top portion and a bottom portion, wherein said top portion of said sole member includes a toe receiving portion, a mid-portion, and a heel receiving portion;

a foot retaining member coupled to said sole member;

said heel receiving portion including a cavity formed in and extending into said sole member from the top portion of the heel receiving portion of said sole member, wherein the cavity has a width and length that is less than the width and length of the heel receiving portion of the sole member; and

a heel contact member coupled below a heel support surface of the heel receiving portion of said sole member in a manner that biases a portion of the heel contact member outwardly from said cavity, wherein an uppermost surface of said heel contact member is at least partially retractable into said cavity below the heel support surface of the heel receiving portion of the sole member and against a force applied to said heel contact member, wherein the heel contact member is comprised of a lever or a loop, wherein when the heel contact member is in a retracted position a heel of a user is supported by the heel support surface.

14. The device as recited in claim 13, wherein at least one end of the lever or loop of said heel contact member is coupled to said sole member within said cavity.

15. The device as recited in claim 13, wherein said heel contact member is completely retractable into said cavity under the applied force.
