Tennis shoes
Technical field
The present invention relates to sport footwear, be specifically related to tennis shoes.
Background technology
One of major function of sport footwear exactly will be for foot provides good stable property in violent motion process, thereby avoids ankle injured at the volley.The anatomical structure of ankle and foot is as shown in Figure 1; Form by anklebone 10, calcaneum 20 and shin bone 30, fibula 40 and foot bones 50 combinations; The upper end of anklebone 10 is positioned in the fossa glenoid that is formed by shin bone 30 lower ends and fibula 40 lower ends; The lower end of anklebone 10 is connected with calcaneum 20, and this unique construction makes ankle become a very stable articulation structure.8 times of body weight when 1.5 times body weight was with running when ankle and foot will bear on foot in strenuous exercise's process, owing to the moving condition polytropy, can be destroyed this rock-steady structure of ankle, finally possibly cause the foot movement damage.
Different motions has different features separately, and the impact that ankle receives also is not quite similar, and therefore, to different motions the use that matches with it of special sport footwear is arranged all on the market.For tennis; Than other outstanding features of moving the most is exactly need be to judging accurately from the ball of different directions and movement pace thereupon; Especially in the left and right sides during break-in; Can produce great pressure to ankle, thereby destroy this rock-steady structure of ankle, finally possibly cause the foot movement damage.
Summary of the invention
Technical problem to be solved by this invention is to solve the easy injured problem of ankle when wearing the tennis shoes motion.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted provides a kind of tennis shoes; Comprise sole and be connected the upper of a shoe on the sole; The heel opening part of said upper of a shoe is provided with soft neckline, is sewed with V font reinforcing band on the left and right lateral surface of said counter upper edge and neckline intersection respectively.
In such scheme, the material of said V font reinforcing band is TPU.
In such scheme, the width of said V font reinforcing band is 2-4cm.
In such scheme, the rear end of said V font reinforcing band connects as one.
In such scheme, the high 0.2-0.5cm in upper edge of the aspect ratio V font reinforcing band of said neckline front end, the high 1-2cm in upper edge of the aspect ratio V font reinforcing band of neckline rear end.
The present invention, outside vamp adopts the V font to stablize the reinforcing band design in the counter neckline ankle, can control ankle and excessively overturn to inside and outside both sides, keeps the stability of ankle, and ankle is injured when avoiding wearing the tennis shoes motion.
Description of drawings
Fig. 1 is the anatomical structure sketch map of ankle and foot;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is made detailed explanation.
As shown in Figure 2; The present invention includes sole 1 and be connected the upper of a shoe 2 on the sole 1; Heel 21 opening parts of said upper of a shoe 2 are provided with soft neckline 22, and the heel 21 general leathers that adopt are processed, and neckline 22 is made up of soft sponge or the silk flosssilk wadding of poromeric material parcel; Be respectively equipped with V font reinforcing band 23 on the left and right lateral surface of the upper edge of counter 21 and neckline intersection, V font reinforcing band 23 is made with the upper edge of heel 21 and is one.
The material of V font reinforcing band 23 is TPU (a TPUE rubber), and width is 2-4cm, because the hardness of V font reinforcing band 23 is greater than heel 21; And width with 2-4cm; Therefore, can control ankle and excessively overturn, keep the stability of ankle to inside and outside both sides.
The high 0.2-0.5cm in upper edge of the aspect ratio V font reinforcing band 23 of neckline 22 front ends; The high 1-2cm in upper edge of the aspect ratio V font reinforcing band 23 of neckline 22 rear ends; The rear end of V font reinforcing band 23 connects as one, and this design makes dress more comfortable on the one hand; V font reinforcing band 23 can intactly wrap heel on the other hand, improves the stability of ankle and foot when motion.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under enlightenment of the present invention, making, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
