Benefits of technology

"The present invention aims to apply ankle support technology to pull-on leather or synthetic fabric boots, such as those used by firefighters, to provide better security and prevent the boot from coming off or lifting from the heel while walking, running, or suspended. The invention includes a self-fastening system with an ankle clip that securely holds the foot in position and automatically closes down against the ankle once the foot is fully inserted in the boot. Additionally, the invention also provides a safety backup by ensuring the foot remains well anchored even if the laces become loose over time."

Problems solved by technology

Over time, the laces will have a tendency to loosen and while commonly accepted that a re-tightening of the laces should be done periodically, it cannot be expected.

Embodiment Construction

[0018] As will be seen hereinafter, the present invention generally relates to the adaptation of form fitting ankle support material within “bunker style” boot for the specific purpose of maintaining maximum boot / foot contact that is, in the contact between the heel of the foot and the sole of the boot during walking or running motion and when suspended.

[0019] Bunker, pull-on styles leather (or synthetic fabric) boots are characterized by the fact that they do not make use of any fastening system. Boots are pulled on and expected to maintain good integrity principally through the design of the boot.

[0020]FIG. 1 illustrates a conventional bunker type boot 10 having no harnessing or fastening system. As depicted by arrows 11, the heel is free to move upwardly away from the insole 12 of the boot 10 while walking. As shown in FIG. 2, the present invention overcomes this drawback by integrating an ankle support 20 into the upper of a boot 22, the ankle support “clipping” about the wear...

Abstract

A bunker style pull-on boot comprises a special ankle support designed to conform to the natural curvature of the human foot. The support wraps around the entire back half of the ankle area. As an integral part of the boot, it provides a grasp of the entire ankle area to securely anchor the foot into the boot to prevent heel lift when walking or running.

Description

RELATED APPLICATIONS [0001] This is a continuation of U.S. Provisional Patent Application No. 60 / 557,685 filed on Mar. 31, 2004BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to footwear and, more particularly, to a system to limit up and down movement of the heel in pull-on boots having no harnessing systems. [0004] 2. Description of the Prior Art [0005] Traditionally, rubber or synthetic rubber has dominated firefighter footwear boots in the style commonly referred to as “bunker style”. This styling is a pull-on and does not make use of any harnessing system such as laces or zippers. The reason for this popular style is that firefighters, responding to an emergency call, do not have time to lace up boots. The notion of pull-on remains embedded with over 80% of the market. By convention, leather (or synthetic fabric) boots for the fire service provide the same styling. Given the nature of these materials, they cannot be manufactured...
