Footwear and conventional footwear according to the embodiments of the invention manufacturing are experimentized.Carry out two different tests, accuracy test and crooked test.In each test, a goal is set, it is partly stopped by the wall from gap, goal 9m.This wall and goal are extended abreast and are departed to surpass a goal post.This wall is designed to simulate a row defender, as occurring in football (or Association football) match.Association football is placed on the position (from the about 19m of goal face) of wall precontract 10m, and wears every pair of footwear by a footwear sportsman and play and hit, footwear in each sportsman at random by turns.
In accuracy experiment, the square of 0.5m * 0.5m of top corner of goal face of the end of the goal post that is covered by wall is selected to be positioned in the target area.Discovery is better than conventional footwear according to the footwear performance of embodiment of the invention manufacturing.On average, footwear carried out according to the preferred embodiment of the invention plays the center that makes that ball drops in the target area and head for target is regional of hitting.On the contrary, on average, the outside that makes ball drop on the target area is hit in playing of conventional footwear.
In curve test, the sportsman is required to play batting and makes ball draw curve to walk around the end that is extending the wall that exceeds goal post and go forward side by side into the front, goal.Can find, will be better than conventional footwear at the quantitative aspects of formation curve according to the footwear of preferred embodiment of the present invention manufacturing.
In addition, can be by finding in two tests, make according to a preferred embodiment of the invention footwear generated plays to hit on the whole and hit more stable than playing of conventional footwear.
Thereby, on accuracy, flexibility and the stability of ball, provide the control bigger than conventional footwear according to the footwear of the embodiment of the invention.Thereby, play the ball that hits under severeer constraint, be more prone to hit the mark zone (for example the part of goal face or with the member's of team foot) and result more reliably is provided according to the footwear of the embodiment of the invention.
Figure 13 is the side view of sneakers 600 according to another embodiment of the present invention.Footwear 600 have projection 602, and this projection 602 is identical with projection 35 functions of Fig. 4 A.In this embodiment, footwear 600 comprise throat zone 607, and this throat is passed the ridge 613 in throat zone 607 with having elastically deformable ground strip component or horizontal expansion.Thereby the V-shaped groove 750 that inclination is provided forms the inclined support surface 760 of ridge 613, as shown in figure 14.Groove 750 and supporting surface 760 help to increase the deflection of ridge 613 and are applied to the amount of the power on the ball 620 thus during contact-enhancing.As shown in figure 15, because the space that groove 750 is provided, ridge 613 is out of shape to a greater degree than common long arc 614 (as Figure 14).Thereby supporting surface 760 offers the elasticity of ridge 613 increases when contacting with ball 620, except the energy of being stored, ridge 613 can hit energy and ball speed thereby generate bigger playing from because the power of the deflection of the ridge 613 of groove 750 caused increases is applied on the ball 620.
In modification, ridge 613 can turn forward towards toe, as shown in figure 16, with the radian of the distortion 614 of further increase projection 613, stores thus and discharges the energy of higher level and more power is applied on the ball 620.
As another modification among Figure 17.In this embodiment, in the contact portion of ball towards ridge 613, ridge 613 has harder and more resilient material layer 615.The elasticity that this ridge 613 is increased means the more power of needs so that the energy of ridge 613 distortion and therefore increase can be provided for ball 620.In addition, the support pad 617 by the elastic caoutchouc manufacturing wherein is filled with resilient gel, or the space of inflation, and it can be arranged in the groove 650 to strengthen the energy of storing and to transmit its energy to ball 620.Selectively, deformable resilient member or class spring mechanism can be used to support ridge 613.Elastic strip 615 and support pad 617 boths can be independent use, rather than as the use together among Figure 17.
It should be noted that groove 750, elastic strip 615 and support pad 617 (or class spring mechanism), shown in above figure, can divide in other all previous embodiment that are applied to a first aspect of the present invention.That is, single contoured pattern can be used groove 750, elastic strip 615 and/or support pad 617 (or class spring mechanism).
In another aspect of the present invention, one or more projection or one or more contoured pattern removably are connected in vamp and maybe can use in being used for the complete element of assembly to improve traditional footwear.Projection or contoured pattern can be fixed or removably be connected on the installed surface, and installed surface removably is connected in vamp.In another embodiment, the ball chain of command can be connected with zip, suspension hook and pile fastener or any other conventional method.For example, the ball chain of command can be rolled up to current vamp, as dismountable crust.Thereby single contoured pattern can replace an other sportsman can adapt to its to the control area of ball to be fit to its distinctive demand and needs.
Selectively, any in vamp or ball chain of command, projection or one or more the contoured pattern can integrally be moulded with sole.
