Description
Technical field
The present invention relates to a kind of insole, more particularly to a kind of snowfield sport shoe-pad.
Background technology
In order to experience the natural snow brought in the ice and snow world interest, have a taste of Ice & Snow Culture landscape heartily, more and more people's ginsengs
In being moved to snowfield.Other entertaining movement meetings etc. no matter are run, jump or carried out in snowfield, and people avenge in experience
When ground moves the joy brought, snowfield movement is because the factor of environment also has great requirement to the dress of players, in order to more
The good protection foot of oneself, to foot it is warming be it is essential, in addition snowfield, which moves, must also pay special attention to anti-skidding, therefore market
On have the insoles of a variety of suitable varying environments.
Insole be apply very universal articles for daily use, by effect point, insole can be divided into health insoles, functional insole and often
Advise insole.The structure of traditional sock is that the sewing of multilayer cloth is suppressed into either multilayer leather, has centainly soft
Softness and shock absorbing effect substantially conform to general wear shoes demand.But emergency stop, zig zag, the urgency in snowfield movement add
During speed etc., traditional sock is then not suitable for, and is had as a drawback that:One, traditional sock damping, shield foot act on poor, snowfield
When movement, foot's half sole and followed by bottom impact force it is big, traditional sock be difficult to absorb in walking, motion process to foot bones produce
Raw impact force, it is difficult to protect vola bone, ankle-joint and knee joint;Secondly, snowfield movement likely results in because of motion intense
Foot is perspired, if sweat is discharged can lead to the ice-cold danger for having frostbite of foot not in time after perspiration, and traditional sock cannot allow
The air in vola circulates with external, increasingly moister in shoes after long-time use, increasingly heavier, and bacterium, fungi grow, damage
The sole of sporter;Thirdly, traditional sock upper side it is relatively flat, unobstructed at left and right sides of insole, rapid traverse or when slowing down, foot exists
It is easily ejected to the left and right sides of shoes in shoes, be easy to cause vola bone, ankle-joint and kneed injury;Four, conventional footwear
Pad is acted on without health care massage, can not be alleviated medicine, be caused sports fatigue, is eventually led to people and is unwilling to participate in snowfield fortune
It is dynamic;Five, traditional insole is without heating function, to winter, in equal public transport or on foot when can all feel that foot is cold, if wanted
It is that skiing or outdoor sports will obviously be more serious, traditional sock does not have the works such as improvement blood microcirculation, anti-inflammatory, analgesia
With, cannot give sporter's foot strip come it is warm.
