Abstract

A system for securing shoes to the feet using a one pull shoe closure arrangement. Each embodiment of the system uses a squared-cord arrangement that extends between the lateral and medial sides of the shoe. The various embodiments arrange a single draw strap connected to one or more squared-cord portions to draw in and tighten the sides of the squared-cord arrangement. A single pull strap in a first embodiment is redirected from a lateral orientation to a longitudinal orientation where it is drawn back and secured on the heel portion of the shoe. Alternate embodiments pull a shorter draw strap laterally to a point of securement on the side of the shoe. Further alternate embodiments pull a draw strap longitudinally along a midline at the top of the shoe to a point of securement back onto the squared-cord arrangement.

Claims
