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.
