According to a survey of over 700 fashion women by ergonomics researcher Carter Craigin of California State University in the United States, more than 70% of women like to wear heels with heel heights of about 6 to 7 centimeters. Because it can make the back of the instep elegantly arched, so that the foot appears more compact, the ankle, calf, thigh muscles can be tight, forming a beautiful leg lines, buttocks muscles will also be tightened, seem more sexy. However, Carter's ergonomic study showed that the heel is best at a height of 3 cm. Wearing high heels of more than 6 cm will increase the burden on the cheekbones and knees, and the muscles in the calf, back, etc. will be very fatigued.

Carter also suggested that women should always have a pair of soft-soled shoes or low-heeled shoes in their office. When they are working, they should be replaced so that their feet can enjoy a relaxed feeling. The most important thing is not to wear high heels every day, it is best to wear low-heeled shoes.
