Sometimes the shoes are only a few months old, but they are badly worn and the soles are so worn that they are crooked.
There are times when this may signal the onset of a disease.
Generally speaking, normal shoe wear should be concentrated in the forefoot, big toe, base, and outer heel area, and the degree of wear on both sides is basically symmetrical, with relatively even wear on the rest of the sole.
If the position of severe wear deviates, or there is wear asymmetry, or a new pair of shoes in three months wear more than 20% to 30%, then it can be judged abnormal.
These abnormalities may indicate the occurrence of certain diseases depending on the location and condition of the wear:
1. Asymmetric wear
Asymmetric wear generally occurs in the uneven stress on both knees, the most typical symptom is the long and short legs.
Long and short legs are prone to lumbar deformities if not supplemented by insoles.
In addition, when a foot is injured, we will intentionally avoid exerting force on the injured side.
In the long run, a protective limp will be formed, which will also result in different wear of the soles of both feet and may also cause lumbar deformation.
2. Wear and tear on the outside of the big toe
Wear and tear on the outside of the big toe could be due to a hallux valgus.
A hallux valgus is a common foot deformity in which the toe is tilted outward by more than 15 degrees.
The main cause is a dislocation of the joint at the base of the big toe, which causes the big toe to curve outward.
In addition to congenital problems, a sedentary lifestyle and frequent wearing of high-heeled shoes are also causes of hallux valgus.
It is recommended to wear fewer shoes with pointed toes and high heels, and not to be sedentary.
3. Wear and tear on the inside of the sole
If the inside of the heel and forefoot of the shoe sole are severely worn, you may have flat feet.
In individuals with flat feet, the foot rests entirely flat on the ground during standing and walking, lacking the natural arch in the forefoot. This condition is often accompanied by inward rolling of the foot, placing significant stress on the inner side of the sole and resulting in notable wear and tear.
If the flat foot is serious, it will form an O-shaped leg, which may lead to knee pain accelerate the degeneration of joints, cause lumbar spine discomfort, and so on.
4. Wear and tear on the outside of the sole
If the outside of the heel and forefoot of the shoe sole is severely worn, the force is often opposite to that of flat feet, which is commonly seen in high-arched feet.
High-arch feet can easily lead to joint sprains and injuries, and in serious cases, they can also cause arthritis, leading to long-lasting pain in the bones when sitting or standing, and the formation of X-shaped legs.
