Abstract

A closure system for a shoe includes a single shoelace which can be secured and tightened through the use of one hand. The shoe includes a button around which the shoelace is wrapped to facilitate easy removal of the shoe. In one embodiment one end of the shoelace is secured under the upper of the shoe near the toe and a second end of the shoelace is secured in a slider that is slidably mounted on the rear of the shoe to provide micro-adjustments of the tightness of the shoe. Alternatively, the shoe includes a strip of piping around the rear of the shoe and a slider in which the second end of the shoelace is secured slides along the piping when the user wants to make micro-adjustments.

2. The shoe of claim 1 , further comprising a ridge formed in a heel tab of said shoe for preventing said shoelace from sliding up said heel tab.

3. The shoe of claim 1 wherein said first end of said shoelace is secured under one of the two flaps and defines a second position along the shoe length axis, the first eyelet defines a first position along the shoe length axis, the foremost point defines a third position along the shoe length axis, and the second position is spaced from the first position in a direction along the shoe length axis from said first position to said third position.

4. The shoe of claim 1 , wherein said first end of said shoelace is threaded under one of said two flaps and defines a second position along the lateral-medial axis, the first eyelet defines a first position along the lateral-medial axis, a third eyelet in one of the first and second series of eyelets which is opposite the first eyelet along the lateral-medial axis defines a third position along the lateral-media axis, and the second position is spaced apart from the first position in a direction along the lateral-medial axis from the first position to the third position, and wherein the second position is located between the first position and the third position along the lateral-medial axis, said first end of said shoelace being folded over said shoelace.

5. The shoe of claim 1 further comprising a button secured to an upper of said shoe and wherein said shoelace is capable of being secured around said button.

6. The shoe of claim 5 wherein said button includes a top button and a base button, said top button being removably secured to said base button.

7. A shoe, comprising:

a rearmost point and a foremost point defining a shoe length axis from the rearmost point to the foremost point;

two flaps with a first of the two flaps positioned on a lateral side of the shoe and a second of the two flaps positioned on a medial side of the shoe, wherein the lateral side of the shoe and the medial side of the shoe define a lateral-medial axis;

a first series of eyelets in the first of the two flaps;

a second series of eyelets in the second of the two flaps;

an opening configured for insertion of a wearer's foot, said opening having a lateral side and a medial side;

a shoelace having a length sufficient to be threaded alternately between said two flaps through the eyelets in said first and second series of eyelets;

a first end of said shoelace being securely fixed at a location near a first eyelet, wherein the first eyelet is an eyelet from among said first series of eyelets and said second series of eyelets which is located closest to the foremost point along the shoe length axis, said shoelace also being alternately threaded through the eyelets in said first and second series of eyelets;

a second end of said shoelace being threaded under one of said two flaps through a second eyelet, wherein the second eyelet is an eyelet from among said first series of eyelets and said second series of eyelets which is located closest to the opening configured for insertion of a wearer's foot, said second end of said shoelace being secured to a slider which is slidably mounted over a guide positioned around a heel portion of said shoe, said slider being slidable over said guide around the heel portion of said shoe; and whereby said slider is adjustable by sliding said slider over said guide to tighten and loosen the shoe, the shoe further comprising a sole, wherein the slider is not located in the sole.

8. The shoe of claim 1 , further comprising a sole, wherein the sole and the opening define a vertical axis from the sole to the opening, the slider and the guide define a second position along the vertical axis, the sole defines a first position along the vertical axis, the opening configured for insertion of a wearer's foot defines a third position along the vertical axis, and the second position is spaced apart from the first position in a direction along the vertical axis from the first position to the third position.

9. A shoe, comprising:

a rearmost point and a foremost point defining a shoe length axis from the rearmost point to the foremost point;

two flaps with a first of the two flaps positioned on a lateral side of the shoe and a second of the two flaps positioned on a medial side of the shoe, wherein the lateral side of the shoe and the medial side of the shoe define a lateral-medial axis;
