Abstract

A system for securing shoes to the feet utilizing a one or two pull fit adjustment set of straps. The embodiments utilize a number of straps, some variable in length, positioned at select points across and around the top and sides of the shoe. At least one strap in the system provides an adjustable length whereby all straps may be drawn together to tighten the shoe, preferably in both a horizontal and a vertical direction across the profile of the shoe. The system utilizes a variety of strong, lightweight, nylon buckles, strips, anchor loops, permitting attachment and motion of the adjustment straps over the top and sides of the shoe. Included are three-point attachment embodiments, as well as two-point attachment embodiments, most with a one pull adjustment structure. Most embodiments are on the medial side of the shoe although some may be implemented on the lateral side.

Claims

1. A system for securing a shoe to a foot utilizing a single-pull fit adjustment motion, the shoe having a length and a width, the system comprising:

(a) a buckle component positioned in a generally centered location on a first side of the shoe;

(b) a first strap extending from a first attachment point on a toe portion of a second side of the shoe, to the buckle component on the first side of the shoe;

(c) a second strap extending from a second attachment point on a middle portion of the first side of the shoe to the buckle component; and

(d) a variable length strap extending longitudinally from a third attachment point on a back upright heel portion of the first side of the shoe, slidingly through the buckle component, to an adjustment mechanism fixed on the first side of the shoe, the adjustment mechanism alternately releasing and securing the variable length strap along its length, the variable length strap longitudinally aligned and parallel with the length of the shoe.

2. The system of claim 1 wherein the shoe has a medial side and a lateral side and the first side of the shoe is the medial side and the second side of the shoe is the lateral side.

3. The system of claim 1 wherein the first strap further extends slidingly through the buckle component to a fourth attachment point on the second side of the shoe.

4. The system of claim 3 wherein the shoe has a tongue, the tongue comprising a plurality of retention channels, the retention channels slidingly engaging the first strap at points where the first strap crosses over the tongue.

5. The system of claim 3 wherein the first, second, third, and fourth attachment points each comprise a removable connector component having a first portion fixed to the shoe and a second portion fixed to the end of the associated strap.

6. The system of claim 1 wherein the shoe has a tongue, the tongue comprising a plurality of retention channels, the retention channels slidingly engaging the first strap at points where the first strap crosses over the tongue.

7. The system of claim 1 wherein the adjustment mechanism comprises hook and loop material surfaces positioned along the length of the variable length strap.

8. The system of claim 1 wherein the buckle component comprises a cinch buckle and the adjustment mechanism comprises frictional surfaces on the cinch buckle.

9. The system of claim 1 further comprising a retention loop positioned adjacent the third attachment point on the back upright heel portion of the first side of the shoe, the retention loop positioned to retain a non-fixed end of the variable length strap after the adjustment mechanism secures the variable length strap.

10. The system of claim 1 wherein the buckle component comprises a triangular ring.

11. The system of claim 1 wherein the buckle component is movable over the first side of the shoe.

12. The system of claim 1 wherein the first, second, and third attachment points each comprise a removable connector component having a first portion fixed to the shoe and a second portion fixed to the end of the associated strap.
