Description
Technical Field
The invention relates to an insole, in particular to a riding special insole.
Background
The cycling exercise has the advantages of no time limit and no speed limit. The bicycle can not only reduce weight, but also make the stature uniform. Since cycling is a sport that requires a large amount of oxygen, it can also strengthen cardiac function, while also preventing hypertension, sometimes more effectively than drugs. The blood vessels can be compressed by riding the bicycle, so that the blood circulation is accelerated, the brain intakes more oxygen, and the brain feels clearer by inhaling a large amount of fresh air.
The sport experts point out that due to the special requirements of cycling, the arms and the trunk mostly work statically, the two legs mostly work dynamically, when blood is redistributed, the blood supply of the lower limbs is large, and the change of the heart rate is different according to the speed of pedaling and the fluctuation of the terrain. The inside of the body is in urgent need of supplementing nutrients and discharging waste materials, so that the heartbeat is increased by 2-3 times compared with usual heartbeat. By repeating the exercise, the myocardium becomes developed, the heart becomes large, the myocardium contracts forcefully, and the elasticity of the vessel wall is enhanced. Thereby increasing the lung ventilation volume, increasing the lung capacity and improving the respiratory function of the lung.
Cycling is a very good exercise, however, not only does it involve vigorous riding, but also takes care of the correct riding posture and wearing without causing injury to the exercise. A common cloth shoe for sports is mostly tied with shoelaces, and the sole is large and soft, so that the cloth shoe is comfortable, shockproof and stable in walking, but when the cloth shoe is used for riding, the sole is too wide and is easy to be clamped to a crank and a rear lower fork, and the treading efficiency is reduced due to the too soft sole. In addition, as sandals and slippers are not covered enough, not only the shoes may be injured when falling down or sudden braking, but also the soles of the feet are easy to shake during stepping, and the soles are soft, so that the shoes are not suitable for riding. The shoe is suitable for professional riding, the shoe body is narrow, the possibility of clamping the crank and the rear lower fork is reduced, and the shoe can be tightly attached to the sole of a foot so as to reduce the shaking of the sole of the foot during treading. Professional cycling shoes also emphasize a stiff sole to improve pedaling efficiency, but relatively, the harder the sole the more professional the shoe, the more awkward it is to walk.
The insoles are common daily articles, and can be divided into health-care insoles, functional insoles and conventional insoles according to the function. The structure of the traditional insole is formed by sewing multiple layers of cloth or pressing multiple layers of leather, has certain softness and buffering and damping effects, and basically meets the requirement of ordinary walking shoes. However, in riding this particular sport, the conventional insole has the following disadvantages: firstly, the traditional insole has poor shock absorption and foot protection effects, the impact force on the bottom of the half sole and the heel of the foot is large during exercise, the traditional insole is difficult to absorb the impact force on the foot bones during walking and exercise, and the foot bones, the ankle joints and the knee joints are difficult to protect; secondly, the traditional insole has poor air permeability, is easy to breed bacteria and fungi, and is easy to cause foot problems such as dermatophytosis and the like; thirdly, the sole of the cycling professional is narrower than other footwear because of the avoidance of the crank and back yoke when riding and the insole of the cycling professional also requires to be relatively stiff, but conventional insoles are not designed significantly in this respect.
