Standard heel height

Despite the force of gravity and the pressure of the body’s weight on the feet when standing, walking, and running, the human body is in a forward position, in other words, the shoulders are forward of the perpendicular line of the body to the feet. This angle in the natural position, which occurs when standing barefoot, naturally pulls the human body forward to carry the weight based on the force of gravity, and this pressure is completely applied to the spine and back, and this causes back pain when walking barefoot, even in the short term.
The principles and standards for shoe heels to create a right angle between the human spine and the ground and eliminate pressure on the back and spine are 2.2 cm, or 22 mm.
It should be noted that thick shoe soles are not a problem in all cases.

How to calculate the standard heel of a shoe
We measure the heel of a shoe by subtracting the thickness of the sole of the shoe from the toe and from each other.
In some shoe models, a hidden heel is used inside the shoe to maintain the design and style of the model (comfort shoes – college), which must also be included in the standard heel calculation and reach a total of 22 mm.
In shoes manufactured or ordered in Europe, due to the height of their race, the shoe design is basically designed with flat heels. Considering such designs, you will see this in European brands carefully, and in Asia, due to the short height of their race, the designs are mainly designed with high heels.
High-heeled shoes are popular for women with heels of 3, 5, and 7 centimeters, with up to 12 centimeters also available in stores.

Side effects of excessive use of high heels
Long-term use of high heels in women causes the muscles in the back of the foot to shrink. Of course, walking a lot in high heels leads to better balance and faster walking speed.
Frequent use of high-heeled shoes causes the pressure of the body’s weight to be transferred from the heel to the toe, which in the long term causes the toes to deviate and overlap, which in the long term causes the toes to gather into a ball and the user’s foot to become clenched.
Wearing high heels causes the human spine to move forward and the human body to be pulled backward in a circular motion under the command of the brain, which causes back pain and shoe fatigue.
It is recommended that high heels be worn for short periods of time and that standard heels be used to reach the required location.
