KICKING SHOE
An athletic shoe particularly suited for kicking sports comprises an outsole, and upper section and an insole. The insole has at least three compressible layers, the outsole has relatively straight inside and outside edges, as well as a grooved bottom surface. The inner and outer sides of the upper section may also be relatively flat. The shoe may further comprise a padded inner tongue and a flat outer tongue.
This invention relates to human apparel and more specifically to a shoe suited for kicking sports.
BACKGROUND OF THE INVENTIONKicking games are popular pastimes all over the world. Games such as soccer, footbag, and football are well known in North America and Europe. Sepak takraw, a soccer/volleyball combination game, is well established in Asia and is gaining popularity around the world.
Suitable kicking footwear is preferably comfortable, supportive and shock absorptive to reduce risk of injury. A lightweight shoe is preferred, in order to reduce fatigue and facilitate quick movement. It is also advantageous to incorporate some padding or protection to cushion the impact upon the foot. Ideally, the outsole should provide good traction. Further, a suitable kicking surface is needed in order to ensure maximum control when kicking the ball. Some of the above-mentioned features may be difficult to reconcile. For example, padding and protection tends to add weight to the shoe, which must be balanced with the desire for a lightweight shoe.
Accordingly, there is a need for a shoe suitable for kicking sports which is lightweight, padded, supportive, has good traction and provides suitable kicking surfaces.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a kicking shoe that is lightweight, comfortable and supportive. Preferably, the shoe should also provide good traction and suitable kicking surfaces.
A first aspect of the invention provides for a shoe comprising an outsole, an upper section, and an insole, wherein the insole has at least three compressible layers.
A second aspect of the invention provides for a shoe comprising an outsole, an upper section, an insole, a padded inner tongue and a toe area within the upper section, the toe area comprising interior padding.
A third aspect of the invention provides for a shoe comprising an outsole, an upper section and an insole, wherein the outsole comprises an inside edge which corresponds to an inner side of a wearer's foot, and an outside edge which corresponds to an outer side of the wearer's foot, and wherein the inside edge and the outside edge are relatively straight.
A further aspect of the invention provides for a shoe comprising an outsole, an upper section and an insole, wherein the outsole has a grooved bottom surface. The grooves may be zigzag shaped or straight, or both.
While the invention is claimed in the concluding portions hereof, preferred embodiments are provided in the accompanying detailed description which may be best understood in conjunction with the accompanying diagrams where like parts in each of the several diagrams are labeled with like numbers, and where:
According to the present invention there is provided lightweight shoe which may be made from canvas or other light, breathable fabric. The shoe comprises an outsole and insole, and an upper section which constitutes the covering for the wearer's foot. Much or all of the upper section may be padded in order to provide comfort and shock absorption. The shoe may include additional padding in the toe area so as to be weighted forward towards the toe, to facilitate controlled, powerful kicking
An insole comprising at least three compressible layers, preferably made from foam, provides comfort and lateral support, and a choice of arch supports can be provided and readily installed with the insole.
The first, or top, layer of the insole extends the full length of the wearer's foot. It is preferably made from a soft foam such as 3 mm soft density EVA foam. The foam may be covered in anti-odor material. Additional arch support may also be included by incorporating a softer, arch-shaped section of foam into the first layer.
The second layer of the insole also extends the full length of the wearer's foot. It is preferably made from a medium density foam such as 5 mm medium density EVA foam.
The third layer of the insole extends only from the ball to the heel, and is preferably made from a high density foam such as 5 mm harder density EVA foam. The third layer may also be tapered from a minimum thickness near the ball of the foot up to a greater thickness at the heel.
For added comfort, the second and third layers may further comprise relatively non-compressible sections made from cushioning rubber, silicone or air implants and located, for example, at the ball and heel areas of the foot. This provides for better cushioning, support and shock absorption under the high compression areas of the ball and heel.
The second and third layers may be slightly wider than the shoe so that they curve around the foot slightly, thus providing lateral stability for the foot from the ball area back to the heel. The first layer may also be slightly wider than the shoe so as to wrap around the foot slightly, giving the foot a snugger fit and added stability.
A fourth layer may also be present, in the form of a heel cup that extends only along the heel area, and also wraps around the sides of the heel. This serves to provide lateral stability for the back and side of the foot.
The layers all together are designed to, over time, mold to the shape of the wearer's foot, thus providing additional comfort, while still providing cushioning and shock absorption.
The at least three layers of the insole preferably include at least one layer that extends from the heel to the ball of the foot, rather than the entire length of the foot. This results in a shoe which, though appears to be quite flat on the outside, still provides for a lift in the heel. The wearer's heel may be higher than his or her toe, which helps to project the body forward and relieves pressure on the heel and back of the leg.
The shoe fastening means may comprise conventional laces or dual zipper. The dual zipper allows the wearer to put on or remove the shoes quickly, and creates a smooth surface over the bridge of the foot.
A padded inner tongue is located under the fastening means, and a flexible but relatively stiff section, made from, for example, foam, may be positioned between the outer shell and the thicker, softer foam of the inner tongue, under the fastening means, to cushion the impact when kicking, and also to prevent the inner tongue from bunching up. Cushioning on the top of the foot and toes provides for greatly increased comfort, particularly in kicking sports. Padding around the toes and the front part of the foot is also provided, and preferably the inner tongue is continuous with this inner padding.
A removable padded outer tongue can be provided that attaches over the fastening means with hook and loop fasteners after the shoe fastening means are closed. The outer tongue provides added padding, and a smooth kicking surface to allow for increased control when kicking. The top of the outer tongue can be left plain, with no surface design, and thus provide advertising opportunities by allowing for the addition of team, club, school or sponsors' names or logos. The removable outer tongues could potentially become trading items among wearers of the shoes.
The outsole has relatively straight sides along the inside and outside edges of the foot (as compared to conventional shoes, which are shaped to mimic the shape of the foot), so that the shoe surfaces along the inner and outer sides of the foot and angle are relatively flat to allow for good control of the ball when it is kicked. Preferably the outsole is made from natural rubber to provide the best grip possible. Further, the bottom surface of the outsole is flat (i.e. not curved), but grooved. Preferably the grooves include zigzag or wave shaped grooves or straight grooves or both. The grooves create peaks and valleys in the bottom surface of the shoe, and preferably the peaks protrude below the inner and outer edges of the outsole. In the prior art, shoes are often designed so that the bottom surface of the shoe are flush with the edge of the outsole. By contrast, the protrusion of peaks past or below the edges of the outsole may allow for better grip on surfaces such as grass and artificial turf, as well as indoor floors such as cement, wood and tile.
The outsole preferably has distinct edges rather than rounded edges at the heel and sides. A strip of rubber foxing is wrapped around the shoe, and the bottom edge of the foxing meets the edge of the outsole. This is different from prior art shoes in which the outsole may continue past the bottom surface of the shoe over the edge of the foxing.
The sides of the shoe (i.e. the upper section) extend substantially vertically from the bottom of the shoe, while the outsole is relatively straight along the sides of the foot. The outsole may be glued onto the upper section and then wrapped with a foxing band. While this design minimizes weight, it usually does not have flat edges like box outsole shoes (which typically are heavy and curve inward along the side of the foot). The present design, by contrast, provides for relatively flat and straight shoe edges with a lightweight foxing style outsole.
The shoes of the present invention are suitable for a wide variety of sports, especially kicking sports. However, they are also suitable court shoes for sports such as tennis, badminton or volleyball, as well as for skateboarding or even simply as walking shoes.
The insole 2 comprises a third layer 4 extending from the heel 6 of the shoe about halfway along the length of the insole 2 toward the toe 8 of the shoe. The third layer 4 tapers from about a negligible thickness at the front end thereof to about 0.5 cm at a mid-portion designated generally at line A, and then at that thickness back to the rear heel end thereof. The second and first layers 10, 12 extend the full length of the insole 2. The layers 4, 10, 12 are made from a compressible material, preferably lightweight cushion foam material.
As can be seen in the section views of
A removable arch support 20 may also be provided. It may be attached to the insole 2 by, for example, Velcro™ fastening. It may adjusted to be placed in the most comfortable position for the wearer.
The illustrated inner tongue 34 comprises a cushion pad 36 under the canvas outer shell material 14. The inner tongue 34 is located under the laces 30. The inner tongue and interior padding may comprise a single continuous piece, thus eliminating a potentially uncomfortable seam at the end of the inner tongue.
Side ridges 160 extend up from the front-top-sides of the shoe 140 and are configured such that the removable outer tongue 142 will fit between the ridges 160 as illustrated in
When the removable outer tongue 142 is in place it is set down between the ridges 160, and tapers down to the top of the toe portion of the shoe 140 providing a flat surface 162 from the toe to the top of the shoe 140 for improved ball control.
The illustrated top surface 162 of the outer tongue 142 is plain without any design so that teams' names & logos, advertising, and the like may be readily printed or embroidered thereon.
