Some workers wear protective shoes and are particularly prone to wear and heel. This is a normal situation. Shoes are worn and the cost of shoes is very common in life. The wear of the heels can reflect the strength of the soles when we walk. However, if a pair of labor insurance shoes can not be worn in 2-3 months, it is not caused by professional habits, that is, the feet are sick. So going to see a doctor is not only about looking at the feet, but also about the shoes. When a person walks, the force's movement route is followed by the heel, then to the outside of the foot, then to the fifth toe, and finally to the thumb. The heel is the biggest point of focus, and 40% is distributed at the bottom of the heel. When the heel is on the ground, the hind foot is slightly turned outward, and the outer side of the heel touches the ground, causing the ground reaction force to be on the outside of the heel. This is why most people love to rub the heel, especially the outer side of the heel. A small number of people are grinding too much, or the degree of wear is asymmetrical, it is likely that the disease has caused the walking posture to be incorrect.
If the inside of the arch of the labor insurance sole is found to be worn faster, it is mostly flat. The "flat foot" foot has small elasticity, the arch of the foot collapses, and the center of the foot directly contacts the ground, and the inner side of the arch is more likely to wear. Heavy wear, mostly due to excessive arch or hip and knee problems. People with congenital spinal disease or hip dysplasia are more likely to wear on the outside of the heel. When a person with a heel pain or "outer eight-legged" walks, the body's weight will be biased toward the inside of the foot, which invisibly aggravates the wear on the outside of the heel. The heel wears on the outside and is alert to the "eight-legged legs". A person with a figure of eight characters in the walking posture, more pressure on the outside of the foot, will accelerate the wear of the outer side of the heel of the labor insurance shoes. The arch of the foot is too high to grind the outer side of the forefoot, and the person with the thumb valgus often grinds the front inner side; while the overall wear of the labor insurance sole is particularly strong in the forefoot, most of which are cervical or lumbar diseases.
The two shoes have different levels of wear and may be neurological diseases or stroke precursors. Before the stroke of the brain or when there is a nervous system disease, it is often a foot that drags the other foot to walk. Because the two legs move differently, one step is towed, so the one side of the step is worn little, and the side of the drag is worn.
Normal people wear protective shoes, which are within the normal range within half a year of grinding, and sometimes the outer side wears slightly more than the inner side. Under normal circumstances, if the newly purchased labor insurance shoes are worn within half a inch of wearing for half a year, they are generally normal, and those with foot disease will wear out the soles in 2-3 months. A person must have at least two pairs of labor insurance shoes, and each pair of safety shoes should not be worn for more than 3 weeks.
