American scientists warn that women wearing shoes all over the world may cause them to suffer from knee arthritis in later life.
The popular women's shoes now have high and wide heels. Many women buy such shoes to avoid the risk of ankle sprains caused by pointed high heels. But Krecken, a doctor at Harvard Medical School, said that such wide-heeled shoes have the same pressure on the knee as stilettos, causing women to develop knee osteoarthritis at an older age.
Krigen published a report in the British Medical Weekly "Lycotyping", which will be published on the 8th. He said that he investigated 20 healthy women who were wearing their shoes in their 30s.
The average width of the wide-heeled shoes they wear is 4.5 cm, and the fine-heeled shoes are 1.2 cm. The two women's heels have an average height of 7 cm. The two groups of women walked 10 meters each, and Kriging took pictures of their foot movements and exertion. They found that the two shoes had exactly the same pressure on the knees of women.
