Description

TONGUELESS FOOTWEAR WITH A CANOPY

BACKGROUND

[0001] The present invention relates to systems and methods for securely and comfortably fastening tongueless footwear having a canopy.

[0002] As shown in Figure 1, most shoes, e.g., shoe 100, have sides 110, 120 attached to a sole. The sides 110 and 120 are tightened by a fastening system such as shoelaces or straps 130, 140. These straps 130, 140 hold the foot in place, pulling the toes together thus forming a cocoon comprising the front tongue 150 tucked between the sides 110, 120.

[0003] Traditional front tongue and lacing has been an inexpensive commonly used solution to closing sports and casual shoes but exerts unnecessary top down foot pressure and toes squeezed together that does not allow the foot to move dynamically when walking or running. Another common feature of shoes is a plastic rigid heel counter that has been fashionable but serves no functional purpose in helping the foot move dynamically, often causing heel bone problems with repeated run, walking demands.

[0004] Generally, when allowed and which is natural during load bearing exercises, the foot will splay about 15% in width. Many current shoe designs fail to accommodate such dynamic foot movements. The foot is widest at the toes but most shoes are not which causes toenail damage when the foot swells up and presses against the end of the shoe repeatedly.

[0005] Further, most shoe designs require significant physical dexterity and also require significant time to be secured to the foot. Hence wearing and/or changing shoes can be challenging for young children, physically handicapped persons and competitive sportsmen participating in timed competitions requiring shoe changes, such as triathlons. [0006] It is therefore apparent that an urgent need exists for tongueless footwear with a canopy that can be easily and comfortably secured to the foot. This improved tongueless footwear can be fastened and removed quickly and permits the foot to function properly and comfortably during use without undue pressure on the foot.

SUMMARY

[0007] To achieve the foregoing and in accordance with the present invention, systems and methods for securely and comfortably fastening tongueless footwear having a canopy is provided.

[0008] In one embodiment, a tongueless footwear includes a sole, a first side, opposing second side, a canopy and a fastening system. The first side and the second side are coupled to the sole. The canopy is coupled to the first side and configured to extend over the second side thereby providing substantially direct support for the ankle and instep of a user. The canopy is further configured to be fastened to the second side. The fastening system is configured to securely fasten the canopy to the second side.

[0009] In some embodiments, the fastening system includes a hook and a corresponding latch. The fastening system can also include a toggle system having a cord and a plurality of anchors, with each of the anchors coupled to either the canopy or the second side. The cord is configured to be operatively coupled to the plurality of anchors thereby securing the footwear to the user. The toggle system can include a tensioner with a dial for controlling tension of the cord. The tongueless footwear can also include an expandable toe box and/or an expandable heel counter.

[0010] Note that the various features of the present invention described above may be practiced alone or in combination. These and other features of the present invention will be described in more detail below in the detailed description of the invention and in conjunction with the following figures.
