First case: Unreasonable foot loading
Heels are too high, such as more than 7 cm, the forefoot weight will increase, up to more than 80% of body weight, causing pain in the forefoot; reasonable heel height is 2-4 cm, then the front and rear foot weight is about 50%, enough The department feels more comfortable.
Looking at the underside of the shoe, draw a line straight from the midpoint of the heel. The area of â€‹â€‹the sole should be evenly divided so that the force on the inside and outside of the foot is even. Otherwise, one side will experience pain and other problems due to excessive stress.
Second case: Shoes have weak energy buffering effect
When the sole is too hard or too thin, the ground impact acts directly on the foot, making the foot susceptible to fatigue and strain.
The third case: Shoe compression and friction on the foot
If the length or width of the shoe is insufficient, the toes, etc., will be squeezed and rubbed. This will create an anguish that will cause lesions in the affected areas.
Points to note when buying shoes
1. The curvature of the heel and foot recess must meet the foot, and the shin and toe should not touch the shoe. The forefoot must have room for swinging, and the heel must not swing.
2, the ideal heel height between 2-4 cm, preferably not more than 6 cm.
3. For every 1 gram of weight added to the shoe, the burden on the foot is equivalent to adding dozens of grams to the back of the person's back. Therefore, choose lightweight shoes as much as possible.
4, the correct shoes should be from the day of purchase on the fit. Do not think that if you wear it for more than two days, it will not wear your feet. In the painful running-in process, your feet will get a lot of problems and even become ugly. So far, you can't adapt to any pair of good shoes.
