It is very easy to destroy the neck of the boot. Because the height of the insole is the relative height-width ratio of the heel neck, the foot that can be wrapped up in the neck of the walking boot is much less, so you will feel dragged when walking, and the neck of the boot will be worn out more severely.

Precautions for inner heightening insole:

If the heel of a shoe is already very high, then adding a heightening insole will not only not achieve the desired effect, but will also make it uncomfortable to wear, because too high may cause swollen feet.

If the upper of the shoe is relatively low, it is not suitable to put it into the heightening insole. Because the height of the insole may be higher than the height of the shoe itself, it will be very uncomfortable to wear and sometimes it may fall off when walking.

Adolescents are not suitable for long-term use of heightening insoles, which may look beautiful, but it will affect the development of bones to a certain extent.
