Description
Technical field
Reviewed troops special footwear and preparation method thereof the present invention relates to one kind.
Background technology
It is activity that country and one of army have Special Significance to review troops.Mainly completed refering to personnel queue advance training and
Displaying, is different from general training, queue is advanced, and training physical consumption is big, and training strength is high, and footwear comfortableness, durability etc. are needed
Ask higher, it is necessary to carry out special footwear research of reviewing troops, meet the particular/special requirement that queue is advanced to footwear.
Queue training of advancing is included in step and stride.The conventional footwork that soldier advances in step, the essential of exercise is, left foot to
Front steps about 75cm, is landed according to the order of first heel hind paw, while centre of body weight moves forward, method is acted right crus of diaphragm like this,
Gait of march 116~122 step per minute.Stride is mainly used in march-past, and the essential of exercise is that left foot kicks out of about 75 lis to front
Rice, leg is exceptionally straight, and tiptoe is pushed, and sole is parallel to the ground, from the ground about 25cm, appropriate firmly full sole is landed, while body
The body weight heart is moved forward, and method is acted right crus of diaphragm like this, gait of march 110~116 step per minute.More conventional training, to army waiting for inspection's queue
Traveling neat and consistent, the officers and men's action norm that is reviewed requirement tighter, standard is higher.The officers and men that are reviewed add up the daily training time
10 hours, training strength is high, and the physical efficiency to officers and men is a kind of test, for footwear, is also in terms of comfortableness, durability
A kind of test close to the limit.
Conventional footwear is different from, reviews troops and uses footwear, especially square team footwear has particularity and specificity on foot, specifically
Show as：One is influenceed by high pressure training, and footwear of reviewing troops should possess preferable durability.By queue traveling action feature and height
Strength training is influenceed, and footwear of reviewing troops easily is damaged, and concrete condition shows as vamp and broken hole occurs, and sole anti-skid design is smoothed,
Main portions are bosom and sole in toe-cap inboard, boot upper heel.More conventional footwear, footwear of reviewing troops footwear material should possess preferably
Anti-wear performance and resistance to performance of colliding with.Two be that leg of a boot design meets foot motion, improves comfort property.The design of footwear of the reviewing troops leg of a boot should
Softness, taut pin pressing action when facilitating stride, meanwhile, wrapped after upper of a shoe with needing particular design, it is to avoid because of heel during taut underfooting pressure
Material stacking wrinkles and causes mill pin problem.Three are during queue is advanced, and footwear of reviewing troops sole lands megaphonia, clear and melodious.Refer to
Square team emphasizes spring heel position during quick march, megaphonia when the full facies palmaris of sole lands when stride is advanced, clear and melodious, with routine
Sole possesses silencing function and contradicted when making caliga traveling, it is necessary to for this particular/special requirement design specialized footwear sole construction and flower
Line.Four be that square team spring heel can provide human body powerful support on foot.Require that spring heel is hard refering to square team, when walking in step
Human body powerful support can be provided, it is to avoid body rises and falls with the crimp of heel material, and then influence uniform queue effect
Really.By investigation, make caliga special functional demands for army waiting for inspection, it is necessary to carry out special footwear research of reviewing troops.

Mouth edge is fluffed, and sand wound side pin is not answered, and the 1/4 of leather thickness is not to be exceeded in fluffing depth；
2) at upper of a shoe flank position, the viscous viscous polyurethane foam of the heart, heel region that hooks fills out core, is adhesively fixed using PUR, should
It is viscous just, cement；
3) by step 2) processing after upper of a shoe drying, at 80 DEG C dry 1~2min, footwear outer bottom heat 80 DEG C, 1~
2min, then covers last carving by upper of a shoe, set just, set it is flat；
4) rubber outsole is first added in a mold, and polyurethane material is injected between the big bottom of footwear and upper of a shoe and is obtained in footwear
Bottom, rim of the mouth and abutment wall decorative pattern are clear, do not come unglued, and foaming is abundant, and foamed glue is firmly combined with outer layer rubber, not starved, is then gone out
Mould；
5) by step 4) the dress last carving sizing of obtained footwear, dress last carving in place, do not answer wrong number, and cryogenic temperature is -5 DEG C, time
10min；Mouth of a river glue is repaiied, mouth of a river glue should be cut to be repaiied together only, should not injure sole；Appearance modification, vamp throwing polishing is bright, then with footwear
Pad, that is, obtain the present invention and review troops special footwear, as shown in Figure 2.
